IntelliStripe 320 Command Reference
104
Read Binary APDU
Command APDU:
CLA INS P1 P2 Le
D0/D1 B0
xx Adr Len
CLA is always D0 or D1 (the lowest bit specifies the state of C4)
INS is always B0
P1 is ignored
P2 is the address where the read will start
Le is the number of bytes to read, 0 will read 256 bytes
Response APDU:
Data Field (from card)
SW1 SW2
Possible SW1/SW2 combinations:
SW1/SW2 Meaning
9000
Normal completion, no errors
Write Binary APDU
The Write Binary command performs a logical AND of the bits already present in the card with
the bits given in the command APDU. For each bit that is 0 in the command APDU, if the
corresponding bit on the card is 1, it will be written to 0. Bits in the command APDU that are set
to 1 will be ignored, the state of the corresponding bit on the card will not be checked. If there is
a need to set a bit on the card to the value of 1, it must be done using the Erase Binary command
or the Verify command. These commands will cause erasure of more than one bit on the card, so
be careful!

CLA is always D0 or D1 (the lowest bit specifies the state of C4)
INS is always D0
P1 specifies RST and allows bit addressing within the specified starting byte. The bits
shown with x are ignored.
