Introduction to five 13.56Mhz high-frequency electronic tags defined by NFC Forum

NFC (Near Field Communication) is called short distance wireless technology and is a set of communication protocols. NFC technology integrates the functional design of non access card reader/Reader, non access label/Tag and peer-to-peer data exchange! It enables simple and safe two-way interaction between electronic devices. In order to promote the development of NFC technology, Nokia, Philips and Sony established the NFC Forum in 2004. NFC Forum， As the developer of the technical specification, the following five types of NFC tags are defined. The article originates from the fallen fish- https://www.duoluodeyu.com/2687.html

NFC Forum Type 1 label is based on ISO14443A. It has the ability to read and re write, and users can configure it as read-only. The storage capacity is 96 bytes, which is used to store URL or other small amount of data. However, the memory can be expanded to 2k bytes. The communication speed is 106 kbit/s.

Typical chip is Topaz 512 (BCM20203) The article originates from the fallen fish- https://www.duoluodeyu.com/2687.html

The NFC Forum Type 2 label is also based on ISO14443A, and has the ability to read and re write. Users can configure it as read-only. Its basic memory size is 48 bytes, but it can be expanded to 2k bytes. The communication speed is also 106 kbit/s. The article originates from the fallen fish- https://www.duoluodeyu.com/2687.html

Typical chips are Mifare Ultralight/Ultralight C, NTag203/210/213/215/216, etc. The article originates from the fallen fish- https://www.duoluodeyu.com/2687.html

NFC Forum Type 3 label is based on Sony FeliCa system, produced in Japan, and widely used in Asia. The data communication speed is 212 Kbit/s. Therefore, such labels are more suitable for more complex applications and have higher costs. The article originates from the fallen fish- https://www.duoluodeyu.com/2687.html

The typical chip is Sony's FeliCa S series. The article originates from the fallen fish- https://www.duoluodeyu.com/2687.html

NFC Forum Type 4 tags are defined as compatible with ISO14443A and B standards. It is preset as readable/rewritable or read-only during manufacturing. The chip memory is larger, and the communication speed is between 106 kbit/s and 424 kbit/s. It is suitable for many applications.
