How the compatible University/campus DESFire credential (D41/D81 series) works
The University/campus DESFire credential (D41/D81 series) is a 13.56 MHz high-frequency contactless credential read over the ISO/IEC 14443 air interface. Its data structure is Campus access/payment DESFire, agency-keyed AES. 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 University/campus DESFire credential (D41/D81 series) 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 Genuine NXP MIFARE DESFire EV1 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 University card-office systems 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.
