How the compatible Häfele Dialock HH (standalone encoding line) works
The Häfele Dialock HH (standalone encoding line) is a 13.56 MHz high-frequency contactless credential read over the ISO/IEC 14443 air interface. Its data structure is Dialock encoding (distinct line item, PO25121022); Mifare Classic 1K / Tag-it HF-I substrate. 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 Häfele Dialock HH (standalone encoding line) by encoding the identical data structure onto a programmable Genuine NXP MIFARE Ultralight EV1 / Classic 1K chip. Once written, the reader cannot tell the difference between our credential and the original — it presents the same bits, the same facility code, and the same card number. That is what "compatible by specification" means: not a generic look-alike, but a credential engineered to read exactly as the original does.
The Häfele 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.
