Identification cards(ID) only record the card number and cannot write data, working in 125KHz frequency.
Integrated Circuit cards(IC) have writable memory, and the recorded content can be repeatedly erased and rewritten. Its working frequency is 13.56 MHz.
HID cards operate at different frequencies, primarily categorized into Prox (Low Frequency 125 kHz) and iClass (High Frequency 13.56 MHz). HID Prox is for basic access control, while iClass provides enhanced security and functionality for more sensitive applications.
