How the compatible Continental Access / NAPCO (CardAccess 3000, C10202 36-bit) works
The Continental Access / NAPCO (CardAccess 3000, C10202 36-bit) is a 125 kHz low-frequency proximity credential — the band most legacy prox readers use. Its data structure is Continental 36-bit C10202 (16-bit FC + 16-bit CN) + proprietary CICP formats; supports up to 10 user-defined badge formats per panel; legacy + standard 26-bit. 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 Continental Access / NAPCO (CardAccess 3000, C10202 36-bit) by encoding the matching data structure onto a programmable T5577 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 Continental Access 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.
