TLV Data Objects
The only Data Objects that should be returned from the GAA command are AID Tags. The
reader sends out ALL TLV associated with each AID.
The reader sends one or more frames with all the AID TLVs in it. Each AID grouping begins with
the Group Number TLV that this AID uses. The user can use this fact to parse between the AID
groups passed back to the POS.
8.3.8.
Get All Groups (03-07)
