We want to delete and add new data to change all groups, AIDs, and CAPKs currently set up on a device. It appears that there is no command to remove all groups, AIDs, etc.

A: There is no delete all groups command or delete all AIDs command. All AIDs that associate with Group 0x00, 0x04, 0x08, and default Groups are considered System AIDs. System AIDs and their respective groups cannot be deleted, only disabled. 

The example below disables system AIDs: A0000002771010 (Interac, group 0x18). The same format applies to other AIDs and Groups.


send command 04-04, data 9f0607a0000002771010 // For a system AID, the command will set the disable bit in FFE6.(= 0x80)
16:01:30.070 OUT: 5669564f7465636832000404000a9f0607a00000027710101535
16:01:30.071 IN: 5669564f74656368320004000000ae16

send command 04-03, data ffe4011800 // to clear TVLs in group 0x18.
16:02:49.670 OUT: 5669564f74656368320004030005ffe4011800d8fb
16:02:49.673 IN: 5669564f74656368320004000000ae16


Refer to the NEO IDG for more detail about the 04-03, 04-04, and D0-05 commands.
