How the compatible Urmet 1125/50 (intercom token) works
The Urmet 1125/50 (intercom token) 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 Urmet-coded 125 kHz token for Sinthesi/iPervoice 1158-series readers; FDI Matelec branch uses 26-bit prox. 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 Urmet 1125/50 (intercom token) by encoding the matching data structure onto a programmable T5577 / EM4305 · 13.56 MHz smart card chip. Once written, the credential presents the same bits, the same facility code, and the same card number your reader already accepts. That is what "compatible by specification" means: not a generic look-alike, but a credential engineered for the exact format your system expects, matched to your facility code and card-number range.
To order, tell us the part number or format printed on your existing Urmet 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.
