RFID is radio-frequency identification. In vending, it helps identify products and users.
RFID (Radio Frequency Identification) is a technology where a reader picks up data from a small tag by radio, with no contact and no line of sight needed. In vending, it is used in coolers that recognize taken items and in systems where staff pay or log in with a card.
How reading works
The reader's antenna sends a signal, the tag replies with its ID, and the system matches it to a product or user in a database.
Uses
- Recognizing products in vending coolers (publisher's site).
- Staff cards in plants and offices.
- Identifying a technician opening the machine.
Limits
Every item needs a tag, and some packaging, such as metal or liquid-filled, can make reading harder. Tag choice depends on the system.
FAQ
Is RFID the same as NFC? NFC is a type of RFID that works over a very short range.
Does an RFID tag hold personal data? A product tag usually holds just an ID. User cards may be linked to data in the system.
