4.5.4 Programming a Transponder with the AFI Byte
If the transponders will remain on the object when leaving the storage location, they must first be
cancelled. This is generally done by writing to a particular area of the transponder.
The AFI byte (Application Family Identifier) is useful for this purpose, since it is contained in nearly
all transponder models in the 13.56 MHz family. To cancel, simply write a different code to the
transponder than for valid transponders which trigger an alarm.
