Buy RFID Card 125 khz Read Only, A 125KHz Read Only RFID Card is a low-frequency (LF RFID) contactless identification card that operates at 125 kHz and contains a factory-programmed unique identification number (UID) that cannot be modified, rewritten, or erased by the user.

How a 125KHz Read Only RFID Card Works

A 125KHz RFID reader emits a low-frequency radio signal that powers the passive RFID card. The card responds by transmitting its pre-programmed unique ID to the reader, allowing the system to identify the cardholder.
