A 125 KHz RFID card reader is a device that reads the information stored in passive RFID cards. Operating at a frequency of 125 KHz, it is commonly used for low-security applications such as door access control or time and attendance tracking. The reader emits a low-frequency radio signal to activate the card, which then sends back its stored information. The reader is usually connected to a computer or network and can have additional features such as a keypad or display screen.
