RFID – Passive Transponder
21. November 2024
|By TUP Redaktion
Passive RFID transponders obtain their energy for transmitting information inductively from the received radio waves. The amount of data stored is considerably less than with active RFID transponders. A unique identification number (GUID = Globally Unique Identifier) is usually stored in their memory. Some passive transponders are equipped with a rewritable memory.
Compared to active RFID transponders, passive RFID transponders are smaller and lighter, have a short range, an almost unlimited service life and are comparatively inexpensive.

- Memory for unique identification number GUID = Globally Unique Identifier (globally unique number)
- smaller and lighter than active RFID transponders
- short transmission range
- almost unlimited service life
- inexpensive (but currently not cheap enough compared to barcodes)
