How the compatible ICT Protege (LF/Wiegand proximity) works
The ICT Protege (LF/Wiegand proximity) is a dual-frequency credential operating on both 125 kHz LF and 13.56 MHz HF, so the compatible part must carry the correct data on whichever band your readers use. Its data structure is Configurable Wiegand prox (LF); ICT Secured 13.56 MHz smart card / AES-secured smart card is the secure HF variant. 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.
Because the ICT Protege (LF/Wiegand proximity) is a secured smart credential, it is designed so the encryption keys stay under your control. We supply compatible blank credentials built on the matching AES-secured 13.56 MHz smart card / T5577 platform, ready for your access-control system or integrator to enrol exactly as it would credentials ordered through the original vendor's channel. You get drop-in spares and bulk stock at a fraction of OEM pricing — and because your own system writes the keys, every credential inherits your site's security.
To order, tell us the part number or format printed on your existing Integrated Control Technology card, along with your facility code and card-number range, 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.
