How the compatible Hotek (HTK) Classic / Smart / Leonardo / Mini Advance works
The Hotek (HTK) Classic / Smart / Leonardo / Mini Advance is a 13.56 MHz high-frequency contactless credential read over the ISO/IEC 14443 air interface. Its data structure is Hotek lock encoding: HTK Classic & Mini Advance on a 1K contactless smart card; HTK Smart on 3DES memory card ('CSMART'); Leonardo 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 Hotek (HTK) Classic / Smart / Leonardo / Mini Advance 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 1K contactless smart card 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 Hotek Hospitality Group 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.
