When you monitor the card you should first see 10 sets of 0xff being sent to the card. No response is expected from this. You should then see the sequence I listed previously I.E. 0x40, 0x00,0x00,0x00,0x00,0x95 After this should come up to 10 0xff bytes which is attempting to read the status bytes back. For success 1 of these should return 0x01. If only 0xff is returned then the card did not see the initialization command. Paul.
