NFC coil specifies the tag type
NFC coil type 1 is based on type a currently exclusively provided by Innovision Research and Technology Corporation (TopazTM), with a memory of 96 bytes, low cost and wide application.
The NFC coil type 2 is also based on the type a currently available exclusively from Philips (Mifare UltraLight), which has half the memory of the type 1 tag.
The NFC coil type 1 is based on FeliCa and is currently exclusively offered by Sony. It has a large memory (currently 2KB) and a high transfer rate (212KB per second) for more complex applications.
NFC coil type 4 is fully compatible with "dual element" A\/B produced by many manufacturers including Philips (typical products such as Mifare Desfire). The memory is large and the read rate is between 106KB and 424KB per second, suitable for various application.
It's worth noting that the memory of class 1 and class 2 labels is very different from the memory of class 3 and class 4 labels, so they make up 2 broad classes. There is essentially no overlap between the various possible application types.
Mobile phone NFC coil is a new type of mobile phone payment tag in the RFID market. Compared with other RFID cards and special-shaped tags, mobile phone tags are lighter and easier to carry, and are widely used in RFID systems such as membership points and identification. They are attached to mobile phones shell or interior.
