Type 3 is based on FeliCa standard (available by Sony). It operates at a higher data rate
(212kbit/s) and has a larger memory. The basic unit of information used in memory
management is called a block. Each block has a fixed size of 16 bytes. The number of
memory blocks available depends on the chip hardware. A Type 3 Tag has only one
state called “Mode 0”. In this state, the Polling Command, Check Command, and Update Command can be received. None of these Commands change the state of the Type
3 Tag. Memory blocks are not addressed directly but relative to the Service they belong
to. Services are similar to files in a file system. Type 2 tag is suitable for more complex
applications
