Reply To: Ultralight EV1 specific command APDU

[mifaresdk]

Hi Maurice,

using the one-way-counter on the UltraLight EV1 you have to use separate commands. You cannot use

Read

for reading the counter value, you have to use

READ_CNT

. The initial value is 00000000 and you can set any arbitrary value with the

INCR_CNT

command.

For further details of the opcode, please refer to:
