Mainstream contactless smart card IC

9.6.1 Manufacturer block

This is the first data block (block 0) of the first sector (sector 0). It contains the IC

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

9.6.2 Data blocks

All sectors contain 3 blocks of 16 bytes for storing data (Sector 0 contains only two data

blocks and the read-only manufacturer block).

The data blocks can be configured by the access bits as

• read/write blocks for e.g. contactless access control or

• value blocks for e.g. electronic purse applications, where additional commands like

increment and decrement for direct control of the stored value are provided.

An authentication command has to be carried out before any memory operation in order to

allow further commands.

9.6.2.1 Value Blocks

The value blocks allow to perform electronic purse functions (valid commands: read, write,

increment, decrement, restore, transfer).The value blocks have a fixed data format which

permits error detection and correction and a backup management.

A value block can only be generated through a write operation in the value block format:

• Value: Signifies a signed 4-byte value. The lowest significant byte of a value is stored

in the lowest address byte. Negative values are stored in standard 2´s complement

format. For reasons of data integrity and security, a value is stored three times, twice

non-inverted and once inverted.

• Adr: Signifies a 1-byte address, which can be used to save the storage address of a

block, when implementing a powerful backup management. The address byte is

stored four times, twice inverted and non-inverted. During increment, decrement,

restore and transfer operations the address remains unchanged. It can only be

altered via a write command.
