125KHz Card

A 125 kHz, low-frequency RFID card operates at 125 kHz. The card contains a microchip and an antenna that communicate with the RFID reader through electromagnetic fields at this low frequency. These cards are typically passive, meaning they do not have a battery and rely on energy transmitted by the reader to power the card and facilitate communication. Like other RFID cards, 125 kHz cards do not require physical contact. They must be close, typically within a few centimeters, remote, and commonly used in various access control and identification applications.
