Many different HF tags are available and the amount of programmable
memory varies with the tag types. The programmable memory consists of
various fields, such as
♦
User Memory
♦
AFI (Application Family Identifier)
♦
DSFID (Data Storage Format Identifier)
♦ EAS (Electronic Article Surveillance)
Depending on your tag type, all memory fields may not be available.
Refer to the manufacturer’s transponder specification for details about
the available memory fields.
Note: Another memory field is the UID, which is not programmable.
The UID is a unique number that was programmed into the
microchip by the manufacturer and cannot be changed.
