NFC Guide: In-depth Read About Near-field Communication

NFC Guide: In-depth Read About Near-field Communication While NFC is similar in many ways to RFID and its history is based on RFID, it is a separate concept. Where RFID has passive and active tags, active tags can be read from relatively long distances, and NFC, as its name suggests, works in the near-field region of electromagnetic fields. RFID is still around and will be for the foreseeable future. NFC is a direct evolution of RFID, you might consider a parallel branch. At the most basic level, NFC is typically two inductively coupled devices whose communication is performed by modulating the power drawn by the passive devices. Passive RFID absorbs RF power, which is then used to transmit data back to the reader – Active RFID can use its own power source to transmit data back to the reader. As with NFC, there are always exceptions to the rule – Type 5 NFC tags work at longer distances (up to 1 meter). In the most typical implementation of NFC, one device is the active device, acting as a master in communication and creating a modulated RF near field that will power passive slave devices. Active devices usually use the name of the reader, while passive devices are called tags. Common examples of tags include stickers and embedded systems; the most common NFC readers you might see in everyday life are smartphones or payment terminals.   NEAR FIELD COMMUNICATION In typical RF communications, a transmit antenna transmits RF signals into free space, requiring an antenna of at least λ/4 (quarter wavelength) to be effective. When the distance between two RF devices exceeds 2λ (two wavelengths), for example, about 245mm (10 inches) for a 2.4GHz signal, it is usually possible to communicate with each other. NFC instead communicates in the spatial near-field region below λ/2 (less than half the wavelength). The two near-field devices act as two coils of a coupled inductor or transformer wound around a common magnetic core. RFID is still around and will be for the foreseeable future.

NFC data rate The maximum bandwidth supported by the NFC standard is 424Kbit/s, which is about eight times the speed of a traditional dial-up 56K connection. This limitation makes the standard comparable to Bluetooth in performance, at about half the data rate of version 4.0. Unfortunately, the standard has a lot of overhead, and most devices typically run at 50Kbit/s. Even with such limited data rates on the connection, and some ingenuity and creativity, the applications are endless. Since the memory on most tags is relatively limited, there is little need for higher data rates. NFC memory Most models of NFC tags contain 100 bytes to 1KB of memory, although available models have up to 64 KB of memory. These larger storage capacities are typically used for smart cards. While this amount of storage may sound restrictive, it allows for a large number of 8-16-bit (1-2 bytes) sensor readings or data about what the Tag is attached to.   NFC tags, tags and basic ICs are widely used for asset tracking and thus need to be very affordable. If every item in a supermarket had an NFC tag on it, or every piece of clothing in a clothing store, even 50c per tag would quickly become unpopular. Fortunately, the simplicity of NFC makes it easy to produce tags and basic tags, which cost between 10c and 50c per tag, depending on volume. When reading the NFC standards, you will find that they have been built to support a variety of existing standards and applications. Fortunately, for our sanity, few electronic engineers who have worked on mainstream NFC implementations need to understand the depth of NFC tag types. All modern smartphones must support each tag type in order to be NFC-compliant. The functions and characteristics of each NFC IC, whether active or passive, tag or reader, sticker or entire SoC, are clearly stated in the datasheet. Tag Type 2 can meet the vast majority of NFC Forum Tag Type 2 NFC cards, self-adhesive labels and asset tags. Basic information storage and retrieval is possible via NFC communication or an I2C interface for connecting to a microcontroller. Tag Type 4 primarily supports the ability to perform computations on a storage and retrieval basis as well as advanced security features. Finally, if you need to read for a long time and allow the user to interact with the label from a smartphone, you will need a marker type

EPC Codes Describe an IoT RFID Application

How to implement RFID technology in your cases Radio Frequency Identification (RFID) refers to a wireless system comprised of two components: tags and readers. The reader is a device that has one or more antennas that emit radio waves and receive signals back from the RFID tag. Tags, which use radio waves to communicate their identity and other information to nearby readers, can be passive or active. Passive RFID tags are powered by the reader and do not have a battery. Active RFID tags are powered by batteries. The tags contain electronically stored information and are identifiable within a few meters. Unlike barcodes, RFID tags do not need to be within the line of sight of the identifier and can also be embedded within the object being tracked. RFID tags can store a range of information from one serial number to several pages of data. Readers can be mobile so that they can be carried by hand, or they can be mounted on a post or overhead. Reader systems can also be built into the architecture of a cabinet, room, or building. Tag: composed of coupling elements and chips, each tag has a unique electronic code, which is attached to the object to identify the target object; Reader: a device that reads (sometimes can also write) tag information, which can be designed as handheld or fixed; ​​Antenna: transmits radio frequency signals between the tag and the reader. RFID tags are physical carriers of Electronic Product Codes (EPCs) that are attached to trackable items and can be circulated around the world to identify and read and write them. At present, the common coding systems for electronic products are mainly EPC codes supported by Europe and the United States and UID codes supported by Japan. Tag memory is divided into Reserved (reserved), EPC (electronic product code), TID (tag identification number) and User (user) four independent Bank (storage block). Reserved: Store Kill Password (deactivation password) and Access Password (access password). EPC: Stores EPC numbers, etc. TID: Store the tag identification number, each TID number should be unique. User: Stores user-defined data. EPC coding builds a system that lets ‘every commodity speak’ in the world In 1999, a genius professor from the Massachusetts Institute of Technology put forward the idea of EPC open network, which has been widely used in International Barcode Organization (EAN.UCC), Procter & Gamble (P&G), Coke, Wal-Mart, FedEx, Nestle, British Telecom SUN, PHILIPS, With the support of 83 multinational companies around the world, including IBM, this development plan began. In October 2003, the EPC GLOBLE global organization was established internationally to promote the application of EPC and the Internet of Things. At that time, developed countries such as Europe, the United States, and Japan made every effort to promote the application of electronic labels that conform to EPC technology. The US Department of Defense, the United States, Europe, Japan’s production enterprises and retail enterprises have developed a plan to implement electronic tags in 2004-2005. The EPC code is a new generation of product coding system launched by the International Barcode Organization. The original product barcode is only a code for product classification. EPC is to assign a global unique code to each single product. The EPC code adopts a 96-bit (binary) method. coding system. The 96-bit EPC code can assign codes to 268 million companies, each company can have 16 million product categories, and each product category has 68 billion independent product codes. The RFID radio frequency identification system includes EPC electronic tags and RFID readers. The EPC electronic tags are number carriers. Through the RFID readers, the information of the EPC electronic tags can be read, and the information is transmitted to the Internet of Things middleware through the RFID readers. After processing, it is stored in a distributed database. The RFID radio frequency identification system includes EPC electronic tags and RFID readers. ” title_text=”The RFID radio frequency identification system includes EPC electronic tags and RFID readers. RFID systems use radio waves at several different frequencies to transfer data.” title_text=”RFID systems use radio waves at several different frequencies to transfer data.”  The EPC information network system is mainly composed of three parts: EPC information service, EPC middleware and discovery service: EPC information service (software support system of EPC system), which is used to realize the interaction of EPC information by end users in the Internet of Things environment. EPC middleware is the link between the RFID reader and the information system. It is used to realize the standardization of each small application environment or system and the communication between them, and set up a common platform and interface between the background application software and the RFID reader, which is usually called middleware. The EPC middleware realizes the information interaction between the RFID reader and the back-end application system, captures real-time information and events, or upstream to the back-end application database system and ERP system, or downstream to the RFID reader. The discovery service obtains EPC data access channel information based on the electronic product code. EPC information discovery service mainly includes Object Name Resolution Service (ONS) and supporting services. An EPC Internet of Things architecture should be mainly composed of EPC codes, EPC tags and RFID readers, middleware systems, Object Name Resolution (ONS) servers and EPC information services to realize the global Internet of Things. The EPC code has enough coding capacity, from the total population of the world (more than 6 billion) to the total number of grains of rice in the world (roughly estimated at 100 million), and the EPC code has enough space to identify all these objects. In order to ensure the uniqueness of the EPC code, EPC Global allocates its own EPC code through the global coding organizations, and establishes a corresponding management system EPC code consists of version number, product domain name management, product classification part and serial number. EPC coding structure standards include: EPC-64, EPC-96, EPC-256. For example, the wine EPC（Select EPC-64 for EPC ID encoding） label data information is designed as APC+PTC+ATC+UID, and each block is allocated 16b data, which can also be allocated as needed. Among them, APC

NXP High Frequency RAIN RFID Family

NXP High Frequency RAIN RFID Family As we know, RFID chips are the main components of RFID transponder and the core of the whole RFID system. The basic structure of the RFID chip generally contains modules such as RF front-end, analog front-end, digital baseband and memory unit. RFID chips mainly involve frequency bands such as 125KHz, 13.56MHz, 433MHz, 860-960MHz, 2.45GHz and other frequency bands, of which 13.56MHz high frequency and 860-960MHz UHF are the major applications frequency. This article focuses on 13.56MHz high frequency main RF ICs. From the standard protocol, 13.56MHz high frequency is mainly divided into ISO15693 and ISO14443 protocols, the difference between them says that ISO14443 is near-field coupling, ISO15693 is far-field coupling, ISO14443 has encryption function, ISO15693 has good penetration, strong anti-interference ability. Of course, now some ISO15693 chips have also added some encryption functions to expand their application scope, such as BGI Semiconductor ISO15693 to increase the national secret SM7. ISO14443 is also divided into two kinds of ISO14443A and ISO14443B, ISO14443B is more private, and is currently mainly used in the financial field, including ID cards, bank cards, etc. When it comes to 13.56MHz high-frequency chips and manufacturers, we have to mention the word NXP.

Top 10 cool use of NFC tags

Top 10 cool use of NFC tags The power of NFC technology lies in its fast, seamless, and secure nature, enabling connected interaction between smartphones and physical media at the touch of a button. By integrating it into new business applications, such as interactive advertising, membership activation, point rewards, and information sharing on packaging and products, it can provide consumers with a new consumer experience. Merchants can also use it to collect data on every interaction of consumers and gain insight into consumer behavior.   So, in addition to the current application in the field of retail payment and public transportation, in what ways can NFC technology be creatively applied to the interaction with consumers, thus opening up a new business model? Here are 10 examples of innovations from the world’s most innovative companies using NXP’s best-in-class NFC technology, tell me about your use of NFC. #1 Interconnection during the journey – Mini’s NFC car key BMW’s automotive hotspot LTE device is an NFC technology accessory that enables consumers to quickly access the Internet while driving. It allows up to eight smartphones to connect to the vehicle’s WIFI transmitter at the same time, as long as they will have NFC technology-enabled phones with a single touch on the LTE tag on the hotspot. BMW’s Mini F56 uses NFC technology in the car key case, and users can immediately activate and pair Bluetooth through a smartphone that supports NFC technology #2 Cheers to NFC – Supports connected beer machines Guinness Brewery has launched a mobile brand engagement program using NFC. In the UK and Ireland, NXP’s NFC label has been applied to thousands of Guinness beer machines. Consumers can download a mobile app on their smartphone and tap Guinness’s famous harp logo for a chance to win a free 500 ml beer. The use of NFC technology in bars is not limited to beer machines on the bar. Carlsberg Beer has developed a unique “NFC Beer Coaster” that customers in Denmark can use to download the mobile app Crowddit (a mobile app to help you find various bars) and receive promotional information for related venues. Don’t look at the NFC coaster as a small and inconspicuous sheet, it can greatly help the bar increase traffic and sales. #4 Dressed in a way – NFC men’s shirt Four Levent’s men’s shirt comes with an NFC tag on both cuffs.

How much and small are RFID tags

How much and small are RFID tags How many a RFID tag? Given the diversity of RFID products on the market today, in general, providing accurate figures on the cost of different components of an RFID system is an almost impossible task. Therefore, we will provide estimates to try to satisfy your curiosity and provide representation of the cost range for the current RFID market. To date, most companies that sell RFID tags have not indicated prices because prices are based on volume, memory, the packaging of the label itself, and whether the label is a special application or many other variables. In the promotion of RFID tags, the biggest problem is the cost, the price of each RFID tag is 0.3 to 0.6 US dollars. For those high-end products, an increase of $0.5 can be accepted by manufacturers and consumers, because for them, RFID tags are an excellent identification and tracking device, and the convenience and benefits it brings are more cost-effective. However, for medium and low-end daily consumer goods, RFID tags are not easy to accept, after all, no one can accept an ordinary toothpaste that has risen by $0.5 because of the use of RFID tags. Therefore, the cost of RFID tags is a problem that has to be considered. In order to promote RFID on a large scale, it is necessary to reduce the production cost, due to the limitations of the process, the cost of tag chips still needs to be further reduced. The basic RFID inlay consists of three parts: a (silicon) chip, a built-in antenna and a substrate. The price of electronic tags is mainly based on different frequency bands, different antennas, different power supplies, different processes, and different packages. The cost per unit ranges from 0.08 to 0.15. If the label is also embedded with a thermal transfer label, where you can print a barcode, the price rises to about 0.20. Keep in mind that low-frequency and high-frequency labels tend to be a little more expensive than UHF labels. The cost of RFID label includes NRE (Non-Recurring Engineering) costs and production costs, NRE is mainly determined by chip size, complexity and other factors, the main cost of production includes substrate costs, substrate testing costs and packaging costs and other aspects. NRE is a one-time engineering fee, including product development costs, sample tapeout fees, test fees, etc. If you want to set up an RFID Inlay with a logo belonging to your own company, cost of usd1600. What Is the Smallest Passive RFID Tag? RFID tags have the characteristics of persistence, strong penetration of information reception and dissemination, large storage capacity and variety of information. These tiny RFID tags could be worked into any product, that is one of the small tags on the market, measuring just 5*5mm square and 0.7mm thick. Smaller tags have a shorter read range, since they cannot capture as much energy from a reader antenna. For applications beyond standard asset management, the Micro UHF EPC Gen2 Tag can be used in a variety of different ways including: identifying and tracking returnable containers, tools at the work site, pharmaceutical products or even items on a retail shelf. The challenge of small size and material means that the reading range is shorter than that of standard UHF RFID tags, with a range of about 1m, but this depends on the environment and the type of reader used. Ironically, the digital UHF EPC Gen2 Micro RFID Tag can be one of the smallest RFID tags in the market but still be a “giant” in terms of meeting the needs and demands of your project. CONTACT US

Active RFID vs. Passive RFID: What’s the Difference?

Active RFID vs. Passive RFID: What’s the Difference? RFID electronic tag is the common name of radio frequency identification (RFID), which consists of a tag, an interpreter and a data transmission and processing system. Generally divided into active RFID and passive RFID, memory with antenna chips, the chip stores information that can identify the target. The most mature application of RFID technology lies in the management of warehouses, logistics and supply chains to identify the advantages of long distance, fast, not easy to damage, large capacity and other bar codes, which can simplify the complicated process of traditional logistics and transportation, and improve the efficiency and transparency of cargo circulation. Application of RFID Tag. Whether it is active RFID or passive RFID, its role is to identify goods, but their application scenarios are not the same, in the traditional logistics system, active RFID because of the strong signal, the coverage is relatively wide, generally used in warehousing. Passive RFID is often used in transportation, strictly controlling shipments and security.   Passive RFID application scenario Passive RFID technology warehousing is mainly used to track or monitor the shipment of pallets, packaging boxes and goods entering and leaving the warehouse. When warehousing, the goods may already have RFID tags, or they may need to initialize the tags, enter the cargo information, and then paste it on the goods. In the traditional logistics and transportation mode, every time the goods arrive at a transit station, they need to scan the terminal code to confirm that the goods have accurately arrived at the operation center.   If there are different goods on the same car, most of them will use passive RFID tags, because the sensing range of passive tags is relatively small, within 60cm, by scanning one by one, there will be no scanning induction errors.   Specific cases can refer to e-commerce logistics, each piece of goods to the operation center, there will be a special person to scan and identify one by one. The advantage of this method is that the data is accurate and the error is small, and the disadvantage is that if the goods are scattered, the time and cost of scanning one by one are high, and it is easy to damage and lose the goods.   Active RFID application scenarios Active RFID is placed in the warehouse need to monitor and track the goods in the area, according to the site environment in accordance with the radio frequency planning, the deployment of active readers, to ensure the coverage of the range and signal strength, and wireless LAN wireless access point planning is the same reason.   Active RFID sensing range can be as high as 30 meters, since this high-frequency output sensing is so strong, why can not be used for in-transit transportation? The reason is that the current pallet electronic tags are only used for induction identification, and can not analyze and manage the information of the goods, using active RFID sensing, the terminal can not read what the goods on the car are, and it is also very prone to induction errors.   Therefore, in the traditional logistics system, active applications are used in warehousing, and passive applications are used in transportation.   Active RFID and passive RFID have their own advantages and disadvantages, can only be used in specific scenarios, the role is greatly limited. Under the concept of plate transportation, procurement, manufacturing, warehousing, distribution, pallets will follow the flow of goods. If the label on the pallet can be compatible with both active RFID and passive RFID, it can bring great convenience to transportation and warehousing. What Is An Active RFID Tag? Active electronic tag refers to the energy of the tag work provided by the battery, the battery, memory and antenna together constitute an active electronic tag, different from the passive radio frequency activation method, before the battery replacement has been through the set frequency band external information. What Is A Passive RFID Tag? The performance of passive RFID tags is greatly affected by tag size, modulation form, circuit Q value, device power consumption, and modulation depth. Passive RF tag 1024bits memory capacity, ultra-wide working frequency band, not only in line with relevant industry regulations, but also for flexible development and application, can read and write multiple tags at the same time. Passive RF tag design, no battery required, memory can be repeatedly erased more than 100,000 times. So, What’s The Difference Between Passive And Active RFID Tags? ACTIVE RFID     PASSIVE RFID   433MHz and 2.45GHz FREQUENCY 860-960MHz Up to 150 meters READ RANGE Up to 15 meters Typically $15 to $ 40 COST Less than $1 per tag Smaller than business card TAG SIZE Mini size 5*5mm Medium to very large ASSET SIZE Very small to very large Oil, Gas, Construction, Mining INDUSTRY Healthcare, Manufacturing, retail Screws, rivets, zip ties, welding ATTACHMENT METHOD Adhesives, epoxy, zip tie, welding, hanging Internal Battery POWER Powered by RF waves Batteries last 3-5 years and typically can’t be changed PAIN POINT Less effective around water and metal SUMMARY   Active RFID system Extremes long read range Increase tag abilities with partner technologies (gps, sensor, etc) active RFID tag come with battery (3-5years batter life) some active tag may have a sensor too, (track environments, track moisture leves temperature, climate, heart beat, etc) Passive RFID tag smallest tag much cheaper Thinner/Flexible High at just able range tag come with long lifetime   The Classification Details of Passive RFID Tag High Temperature – Certain industries, like healthcare, track the number of cycles that instruments undergo in punishing autoclaves. Specific passive RFID tags are designed to withstand extreme temperatures and accommodate for those types of applications, among others. Rugged – Applications in outdoor environments or tough warehouses need a tag that can withstand snow and ice, dust and debris, or even the crushing forces felt under a tractor wheel. For these applications, a highly rugged passive tag is needed to make the application successful. Size – Some applications

What are the pros and cons of using RFID for Inventory Management?

What are the pros and cons of using RFID for Inventory Management? RFID for Inventory Management is used to recognize and discover unique objects, including products and items. The technology is measured by radio waves that interact between a tag on the product and the reader. In warehouses, distribution centers, and facilities that have deployed automated inventory management technology, barcode labels have become regular operating procedures. But RFID has become a bigger part of the inventory management equation, especially in retail where several big companies are using the tags to track goods at the pallet, case, and even item-level at the retail shelf. While RFID has some big benefits over barcode labels, deciding whether to use the technology in your inventory operations will require weighing the costs and benefits. Below, we’ve outlined some of the pros and cons of using RFID for inventory management.     Features of RFID warehouse management software: Product Warehousing: RFID warehouse management software uses production and manufacturing, purchase of all normal warehousing, return and replacement of goods into the warehouse and other different warehousing methods. Data Sheets: RIFD warehouse management software can customize the setting of basic information such as product information, raw material information, machinery and equipment information. Inventory Transfer: for different libraries in the middle must be transferred, rfid warehouse management software can automatically generate a transfer order number, suitable for different library in the middle of the transfer. Dynamic Inquiry: applicable to the inventory list query, the entry and exit list query, the product type query, the inventory query, and the date query. Market Sales delivery: According to customer orders, use market sales of goods, customers and other data information, apply for purchase and shipment orders to reduce inventory. Warehouse Summary: RFID warehouse management software can summarize the warehouse anytime and anywhere, automatically generate bills, save time and effort in the summary work, when the total amount of inventory is not enough, the mobile phone software automatically warns the information. Data Analysis: You can customize the quarterly reports and inventory tables required for statistical analysis, and see at a glance the property and inventory status.     Pros of using RFID 1. RFID tags can be read from any orientation2. RFID does not require line of sight for scanning. With barcode labels, employees (or fixed position scanners) have to be able to see the label to get a safe scan.3. RFID also improves the visibility of inventory by providing real-time updates and faster scanning.4. It increases inventory visibility and helps you cut labor cost. RFID can reduce labor charges. Labor can account for 50% to 80% of expenses in a distribution center.5. If you are using in-store customer pickup or ship your product from multiple warehouses located in different continents then RFID (Radio Frequency Identification) technology allows you to identify individual products and components and even allows to track it across the supply chain process.6. If you are connecting to omnichannel consumers then RFID is vital, as you need to have access to accurate inventory level across multiple selling points.7. For the right items in the right settings, UHF RFID enables stock-take with >95% accuracy an order of magnitude faster than optical bar codes.8. Using this increased accuracy and addressing stock outs has been shown to drive increased sales of 10%.9. For companies that use returnable containers or pallets, RFID provides a way to track those items across the supply chain, optimize asset inventory, and reduce loss or theft.     Cons of using RFID 1. RFID is not advisable for small scale retailers as the cost attached to the deployment of this technology is high.2. In order to implement RFID, you first need to upgrade your existing inventory management system to support a sensitive technology like RFID.3. RFID tags may also suffer from interference problems. If the tag environment contains a lot of metal, liquids or other sources of radio interference.4. RFID tags can provide much more traceability data than barcodes, but managing all of that data can be a challenge.5. There are also still incompatible standards across different industries, tag types, and in different countries. CONTACT US Facebook Twitter LinkedIn
