The ATR within the PCF2006 payphone/debit card IC is
just a so called “short ATR”. It is 16 bytes long and is stored
in the lower partition of the memory (this ATR is not
defined by ISO).
Main purpose is also to identify the card to the terminal.
The codes currently used have to be applied and are
assigned an organization called ProElectron.
The whole procedure and the contents bases on an
agreement of the main smart card IC manufacturer and
system providers.
Contents of the ATR reflects the following information:
The code is not transparent, but can be traced back.
The major target is here as well to distinguish between
different applications.
All IC maker now are members at ProElectron and are
accordingly prepared, the card manufacturers have not got
active yet. (The number itself might be given to preference,
but there is no guarantee.)
The total memory area from address 0 to 23 is write
protected and read only when delivered. PS programs the
ATR, Fab data and fab key (transport code, 24 bit) during
final test and sets all bits in card data and some of the
count data to “1”.
