Read Binary APDU
Command APDU:
CLA INS P1 P2 Le
00 B0 Adr1
Adr0 Len
CLA is always 00
INS is always B0
P1 is upper byte of address to read.
P2 is lower byte of address to read.
Le is the number of bytes to read
Note that if the address given is outside of the bounds of the card in the reader you may
not get the expected results. If the sum of Le and the address is outside of the bounds of
the card, some of the data will probably represent a wrap-around to the beginning of card
memory.
Response APDU:
Data Field (from card) SW1 SW2
Update Binary APDU
Command APDU:
CLA INS P1 P2 Lc Data Field
00 D6 Adr1 Adr0 Len Data to be written
CLA is always 00
INS is always D6
P1 is upper byte of address to write.
P2 is lower byte of address to write.
Lc is the number of bytes to write.
Data Field contains the bytes to write.
Note that if the address given is outside of the bounds of the card in the reader you may
not get the expected results. If the sum of Le and the address is outside of the bounds of
the card, some of the data will probably represent a wrap-around to the beginning of card
memory.
Response APDU:
SW1 SW2
Possible SW1/SW2 combinations:
