Top Different Types of RFID Chip
RFID tags can be grouped into three categories based on the range of frequencies they use to communicate data: low frequency (LF), high frequency (HF) and ultra-high frequency (UHF). Generally speaking, the lower the frequency of the RFID system, the shorter the read range and slower the data read rate.
Low Frequency (LF) RFID 125K – 134K
- UID: It is the unique identifier of LF tags. Since there cannot be duplicates, this means each tag is unique worldwide. It is factory locked and cannot be changed. Some for read only, some both for read and write.
- Password: A password can be entered so that no unauthorized person can write over the chip.
- Memory: It is designed to write data that users need into 4-byte blocks.

High Frequency (HF) RFID NFC 13.56MHz
- UID: It is the unique identifier of NFC tags. Since there cannot be duplicates, this means each tag is unique worldwide. It is factory locked and cannot be changed. It has a 7-byte memory, which is equivalent to 14 hexadecimal characters. Example: 04 9C 64 D2 45 2B 80
- Password: A password can be entered so that no unauthorized person can write over the chip.
- Memory: It is designed to write data that users need into 4-byte blocks. The standard encoding format supported by all devices is NDEF. You can write URLs, dates, batches, locations, contacts, etc.

Ultra-High Frequency (UHF) RFID 860MHz-960MHz
- EPC: The Electronic Product Code is a universal identifier to provide a unique identity for every object and product. The serial number can be customized. Example: F4500019081201311700680D
- User memory: It is designed to record the data required by users, such as dates, batches and product expiry date.
- TID: It is the unique identifier of RFID tags. Since there cannot be duplicates, this means each tag is unique worldwide. It is factory locked and cannot be changed. Example: E200001908120237172068DA
- Password: A password can be entered so that no unauthorized person can write over the chip.

- NXP Semiconductors
In most cases and applications, standard RF ICs with low memory can be used, low and no user memory be read faster. More specific sectors, such as the automotive, Inventory, healthcare, fleet management, pharmaceutical industry and applications with security needs, require chips with more memory.
