How the compatible Gartner (dual HF + UHF card) works
The Gartner (dual HF + UHF card) is a 13.56 MHz high-frequency contactless credential read over the ISO/IEC 14443 air interface. Its data structure is Gartner dual-frequency card: 1K 13.56 MHz smart card HF + Alien Higgs-9 UHF EPC. When you present a credential, the reader decodes that exact structure and passes it to your access-control panel as a card number it recognises.
We build the compatible Gartner (dual HF + UHF card) by encoding the matching data structure onto a programmable 1K contactless smart card chip. Once written, the credential presents the same bits, the same facility code, and the same card number your reader already accepts. That is what "compatible by specification" means: not a generic look-alike, but a credential engineered for the exact format your system expects.
To order, tell us the part number or format printed on your existing Gartner card, and our specialists confirm the encoding before anything ships. Bulk and reorder quantities are welcome — pricing is a fraction of OEM list, and every credential is verified to read on your existing equipment.
