RFID Card
A radio-frequency identification card used as an access or attendance credential — the terminal reads the card's unique ID wirelessly when held near the reader.
RFID is convenient and fast, but most organizations combine it with biometrics to prevent card-sharing and buddy punching.
Frequently Asked Questions about RFID Card

RFID typically refers to 125 kHz low- frequency cards for access control.NFC operates at 13.56 MHz and is used by smartphones and smart cards.Nialabs supports both.
Can RFID cards be cloned?
Older Mifare Classic cards can be cloned. Mifare DESFire and encrypted cards are far more resistant. Combining RFID with biometrics eliminates the risk of cloned card access.
How far away can RFID be read?
Standard proximity cards work at 3–10 cm. Long-range RFID for vehicle access or parking can work at 1–10 metres depending on reader power and card type.
