What is NFC A and NFC B?
NFC-A and NFC-B refer to the Type A and Type B communication technologies specified in the contactless IC card international standard ISO/IEC 14443. NFC-F refers to FeliCa communication technology, based on the International Standard ISO/IEC 18092 and JIS X 6319-4. NFC-V refers to ISO/IEC 15693-based communication.
What is the most common NFC tag?
NFC Forum Type 2 tag
The NFC Forum Type 2 tag is the most popular type of tag. It offers a solution to a wide range of needs and uses at an affordable price. The type 2 tags are faster than type 1 tags and are used in applications where users need instant communication.
How do I choose an NFC tag?
- Choice of the NFC Tag. Tag positioning.
- Compatibility. The first thing to consider is: which reader will be used to read or write the Tags.
- Available memory. Another important aspect is the user memory, which is the rewritable memory of the NFC Tag.
- Encryption.
- Data retention.
- Read/write cycles.
- Password lock.
- Tag positioning.
What are the different types of NFC?
The types are NFC-A, NFC-B and NFC-F. Refer NFC-A vs NFC-B vs NFC-F for more which describes difference between these signalling types.

From the definitions of the different NFC tag types, it can be seen that type 1 and 2 tags are very different to type 3 and 4 tags, having different memory capacity and makeup. Accordingly it is expected that there is likely to be very little overlap in their applications.
What is the difference between Type A and Type B cards?
Type A smart cards receive bursts of power from the reader while in communication. Type B smart cards are usually called microprocessor cards. Type B cards receive power continuously while they are in contact with the smart card reader. Type B cards handle bit rates up to 847 kilobytes (KB) per second.
What is NFC-B signaling?
The signalling type NFC-B is based on ISO/IEC 14443B. It is similar to RFID type B. Here manchester encoding technique is employed. Here instead of 100\%, AM modulationat 10\% is used. This convention is used to distinguish between binary 1 and 0. 10\% change from 90\% for binay 0 (i.e. low) and 100\% for binary 1 ( i.e high) is used.
