What Is an RFID Key Fob?

An RFID key fob is a compact passive RFID credential that stores identification or application data and communicates with a compatible RFID reader. Its small keychain-style design makes it convenient for everyday access and identification.

RFID key fobs are commonly used for door access control, time attendance, employee identification, membership, hotels, parking, lockers, swimming pools, laundry management, transportation and ticketing systems.

For B2B projects, the most important consideration is not the appearance of the key fob but its compatibility with the existing RFID reader and system.

The appropriate frequency and chip should therefore be selected according to your reader, protocol and application requirements.

Which RFID Key Fob Is Right for Your System?

Match the RFID key fob to your reader—not just the product appearance.

Important: RFID compatibility depends on the reader, frequency, protocol, chip and system configuration.

Not sure which RFID key fob you need? Send us your reader model, existing card/key fob or chip information. Our team can help identify a suitable configuration before production.
