User AIDs
A User AID is an optional AID that is added and/or configured by the user. These AIDs are used
for servicing transactions that are not defined by one of the System AIDs. This determination
needs to be made by the integrator.
The terminal:
•
May modify ANY User AID property
•
May delete a User AID
There is no equivalent to the System AID disable; the User AID either exists, and it is used for
its associated transactions, or the User AID is not present.

Reader Default TLV Group
The reader is provided with a default TLV Group (Group 0) that defines all the properties (with
TLVs) required for a basic transaction. By default, all of the System AIDs except PayPass
System AIDs (MasterCard and Maestro) use TLV Group 0 to define their transaction
processing. By default, MasterCard PayPass System AIDs will use Group 1.
