Are Transponder IDs and Tag Identifiers One and the Same?
How do these differ if they are different? And can they be written by a user or changed?
In the RFID industry, as in other technology sectors, terms are often thrown around loosely. There is no "transponder ID," at least formally. There is the serial number in a transponder, which some may call a transponder ID. A serial number in an RFID tag is sometimes encoded by the chip's manufacturer and sometimes by a user. "Tag ID," a formal term for an identifier written to a chip by a manufacturer, differentiates that chip from all others. The tag ID cannot be written by a user or changed in any way.
I hope to see you at RFID Journal LIVE! 2020 in September.
