8.1.1 Manufacturer block

The first data block (block 0) of the first sector (sector 0) contains the PICC manufacturer

data. This block is programmed and write protected during the production test.

8.1.2 Data blocks

Sectors 0D to 31D contain 3 blocks each and sectors 32D to 39D contain 15 blocks for

data storage. The data blocks can be configured using the access bits as:

• read/write blocks for storing binary data

• value blocks
