IntelliStripe 320 Command Reference
100
Update Binary With Protection APDU
Because of card functionality, this APDU should not be sent until at least one Read Binary
APDU has been sent first.
This APDU will not be found in ISO 7816-4. That is why it has the CLA of D0 (Proprietary).
Command APDU:
CLA INS P1 P2 Lc Data
Field
D0 D8 Adr1 Adr0 Len Data to be written
CLA is always D0
INS is always D8
P1 is upper byte of address to write and must not be greater than ‘03’
P2 is lower byte of address to write.
Lc is the number of bytes to write, 0-1024
Data Field contains the bytes to write. If a byte to be written is already protected, a status
6581 will be returned. Data is written first, then the Protect bit is written with
comparison, assuring that the data being protected is the data you wanted to
protect.
Response APDU:
SW1 SW2
Possible SW1/SW2 combinations:
SW1/SW2 Meaning
9000
