MIFARE Classic® technology operates at a frequency of 13.56MHz and allows for changes to enrolled data using an RFID encoder. HID's Secure Identity Object® (SIO®) technology adds an extra layer of encryption for added security. This RFID badge is also compatible with HID's Prox technology.
The visual aspect of the card can be customized with a high definition printer to add, for example, a passport photo or holograms to avoid counterfeiting.
