How the compatible Deister proxEntry works
The Deister proxEntry 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 deister-own proxEntry credentials use AES-encrypted application + configTool custom keys. 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 Deister proxEntry 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 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.
The deister electronic GmbH format sits among the specialist proximity credentials most card vendors never tooled up to produce — which is why the only other source is usually the original manufacturer, at a steep premium. Supporting these hard-to-find formats is exactly what Security ID Systems specialises in. Tell us the format printed on your card, or send a sample for us to read, and we confirm compatibility before you order.
