현재 NFC TAG는 총 4가지 타입으로 분리가 되고 있습니다.
기반한 프로토콜 및 속도, 용도에 따라 분리 되고 있습니다. 참고 하시기 바랍니다.
가장 범용으로 쓰이는것은 타입2 입니다.
1.    Tag 1 Type:  The Tag 1 Type is based on the ISO14443A standard. 
These NFC tags are read and re-write capable and users can configure the tag to become read-only. 
Memory availability is 96 bytes which is more than sufficient to store a website URL or other small amount of data. 
However the memory size is expandable up to 2 kbyte. 
The communication speed of this NFC tag is 106 kbit/s. 
As a result of its simplicity this tag type is cost effective and ideal for many NFC applications.
2.    Tag 2 Type: The NFC Tag 2 Type is also based on ISO14443A. 
These NFC tags are read and re-write capable and users can configure the tag to become read-only. 
The basic memory size of this tag type is only 48 bytes although this can be expanded to 2 kbyte. 
Again the communication speed is 106 kbit/s.
3.    Tag 3 Type: The NFC Tag 3 Type is based on the Sony FeliCa system. 
It currently has a 2 kbyte memory capacity and the data communications speed is 212 kbit/s. 
Accordingly this NFC tag type is more applicable for more complex applications, although there is a higher cost per tag.
4.    Tag 4 Type:  The NFC Tag 4 Type is defined to be compatible with ISO14443A and B standards. 
These NFC tags are pre-configured at manufacture and they can be either read / re-writable, or read-only. 
The memory capacity can be up to 32 kbytes and the communication speed is between 106 kbit/s and 424 kbit/s.
