Legacy OEM Proximity

continental access compatible card

125 kHz LF C-tier format

A compatible replacement for Continental Access - (covered) — a 125 kHz proximity credential, encoded by specification to read identically on your existing readers, matched to your facility code and card number. Order single spares or bulk quantities at a fraction of OEM list pricing.

How the compatible Continental Access - (covered) works

The Continental Access - (covered) is a 125 kHz low-frequency proximity credential — the band most legacy prox readers use. Its data structure is See 'Continental Access / NAPCO (CardAccess 3000, C10202 36-bit)' entry. 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 - (covered) by encoding the identical data structure onto a programmable T5577 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, 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.

Continental Access - (covered) — common questions

Is this a genuine Continental Access card or a compatible one?

It is an independently manufactured compatible credential — engineered to the same specification as the Continental Access - (covered) so it reads identically on your existing readers, but it is not an Continental Access-branded product. Security ID Systems is independent and not affiliated with Continental Access; your access-control panel accepts the credential exactly the same way.

What chip is the compatible Continental Access - (covered) encoded on?

It is encoded on a T5577 programmable chip. That platform reproduces the original 125 kHz LF data structure precisely, so the credential presents the same information your readers already accept, including the correct facility code and card number.

What frequency and format is the Continental Access - (covered)?

It operates on 125 kHz LF, using see 'continental access / napco (cardaccess 3000, c10202 36-bit)' entry. Matching that exact frequency and data structure is what makes a compatible credential work — a card on the wrong band or bit length simply will not read.

Do you match my facility code and card numbers?

Yes. We encode each compatible Continental Access credential to your specific facility code and the card-number range you provide, so the cards drop straight into your existing system. Send us the numbers printed on a working card, or a sample to read, and we confirm the encoding before production.
