Casi-Rusco Compatible Magstripe Card

Magstripe / LF

A compatible replacement for Casi-Rusco F/2F 12-digit Magstripe — a Magstripe / LF 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 Casi-Rusco F/2F 12-digit Magstripe works

The Casi-Rusco F/2F 12-digit Magstripe operates on Magstripe / LF. Its data structure is 12-digit F/2F (frequency / double-frequency) magstripe encoding, no facility code split, no parity. 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 Casi-Rusco F/2F 12-digit Magstripe 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 Casi-Rusco 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.

Casi-Rusco F/2F 12-digit Magstripe — common questions

Is this a genuine Casi-Rusco card or a compatible one?

It is an independently manufactured compatible credential — engineered to the same specification as the Casi-Rusco F/2F 12-digit Magstripe so it reads identically on your existing readers, but it is not an Casi-Rusco-branded product. Security ID Systems is independent and not affiliated with Casi-Rusco; your access-control panel accepts the credential exactly the same way.

What chip is the compatible Casi-Rusco F/2F 12-digit Magstripe encoded on?

It is encoded on a T5577 programmable chip. That platform carries the original Magstripe / 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 Casi-Rusco F/2F 12-digit Magstripe?

It operates on Magstripe / LF, using 12-digit f/2f (frequency / double-frequency) magstripe encoding, no facility code split, no parity. 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 Casi-Rusco 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.

Why is the Casi-Rusco format hard to find?

The Casi-Rusco format is one of the specialist, proprietary credentials that many card vendors don't offer. Security ID Systems focuses on exactly these specialist and legacy formats, encoding a compatible credential to the exact specification your readers already accept.
