Proximity card, dual. It operates on frequencies of 13.56 MHz and 860 MHz. Designed for cooperation with Mifare card readers (eg KDH-C100M) and long-range readers working in the UHF band (eg KDH-CDZ900). It is worth noting that the number printed on the card is the same for both versions (Mifare and UHF), which makes it easy to add it to the system using the USB administrator card reader - KDH-CADM-M32. The card is of the PVC type and has the option of printing the photo-ID.
