Continental Access / CardAccess (NAPCO) Compatible Cards & Fobs
NAPCO's access-control arm runs on open standards: CardAccess 3000 and CA4K systems overwhelmingly issue plain 26-bit Wiegand credentials, which makes replacements one of the simplest orders in access control.

Continental Access took the interoperable road. Rather than binding customers to a proprietary card, CardAccess panels were built to read standard Wiegand structures — most sites run ordinary 26-bit H10301, and the CA4K generation reads practically any structure an integrator throws at it, from 26 to 256 bits. For a facility manager, that translates to freedom: replacement credentials only need the right format, facility code, and number range, not the right logo. The place to be careful is simply confirming which structure your panel was commissioned on, since CA4K's flexibility means a minority of sites run extended or custom layouts. We confirm that from your panel settings or a working card, then manufacture unbranded, compatible-by-specification cards and fobs programmed to your values — verified against the confirmed structure before shipping, ready to enroll in CardAccess like every credential before them.

What format does CardAccess 3000 use?
Most installations run standard 26-bit Wiegand H10301 — facility code plus card number. The panels also support larger structures, and CA4K systems read a very wide range, so a quick check of your panel's card-format setting (or a sample card) confirms yours before ordering.
Are Continental Access cards proprietary, or will standard 26-bit stock work?
The common deployments are open: a correctly programmed standard 26-bit credential enrolls exactly like OEM-labeled stock, because the panel reads data, not branding. That's a deliberate design choice of the platform and the reason replacements are straightforward.
Can I order by facility code?
Yes — facility code plus card-number range is precisely how batches are specified. Both usually appear in your CardAccess software's credential records or on the printed face of existing cards; we verify against a sample before production.
Do you supply both cards and fobs for these systems?
Both, programmed identically from one specification — clamshells or printable ISO cards for badges and keyring fobs for tenants and contractors, all continuing a single number sequence so your records stay clean.
