Serial
Number
0 or Variable Serial number (or the UID) of the PICC. Length depends on the card detected. If no
card was detected, then a serial number is not returned.
Note:
Most cards use a 4-byte UID, so the data field of the response is five (5) bytes long.
However, some cards with 7-byte UID’s have entered the market (for example, ViVOcard3)
and it is expected that cards with 10-byte UID’s soon becomes available. All of these card
types are handled by this command.
8.12.4.2.
Enhanced Poll for Token Usage
This command can be substituted for the standard
Poll for Token
in any transaction taking
place in Pass-Through Mode. Its differences in operation are noted as above; its other
arguments should be identical to those of the standard
Poll for Token
that it replaces.
Note
: If you use an
Enhanced Poll for Token
command but have set all values in the
Transaction Type field to zero, then the command performs a standard
Poll for Token
instead.
8.12.5.
Get ATR (2C-12)
This Pass-Through command can be used to get the ATR received by the reader from the ICC and SAM
when a Level 1 session was established.
