Communication (Proximity Wireless Communication) is a near-field wireless communication technology with a 13.56MHz frequency band that allows contactless point-to-point data transmission and exchange between electronic devices (within 10cm). We using NFC technology can exchange data close to each other, realize mobile payment, electronic ticketing, access control, mobile identification, security, and other applications. Simply said, the NFC tag is a small chip that can rub input, and you can write some personalized features into it. For example, you write a URL, phone number into, write well, when you want to open this URL or dial you to write in the phone number, you just need to put the NFC tag and your phone’s NFC sensing area, this URL or phone number will automatically appear on your phone, very convenient. NFC technology combines the Reader, tag, and peer-to-peer data exchange! NFC Forum, as the author of the specification, defines the following 5 types of NFC tags.
While tag types 1-4 exist since the early days of NFC definitions in ~2006, NFC forum added the ISO 15693 based Tag Type 5, in June 2015. This means in practice, that tag types 1-4 today are supported by typically all NFC devices, whereas tag type 5 needs to be tested. Typically Android, Windows Phone 10 and iOS ≥ 11 can work with type 5 tags. However, there may be differences in chip types. E.g. while the ISO 15693 chip ICODE SLIx from NXP works on all Samsung Galaxy phone models, including Android 4.x, other 15693 chips require Android 5.x to be properly recognized. iOS 11 requires iPhone 7 and an APP to be installed supporting read-only. Also MIFARE® Classic (not an NFC Forum tag type yet) is only supported by a few phones, depending on which NFC chipset is inside e.g. Samsung Galaxy S3 works well with MIFARE Classic, while Galaxy S4 to S9 do not support it. Most Windows phones support MIFARE Classic, but like type 5 tags, these tags must already contain NDEF formatted data that was written to the tag first in some other way before it can be used with Windows phones.
