Software House CCOTZ 37-bit Compatible Card

125 kHz LF + 13.56 MHz HF

A compatible replacement for Software House (C-CURE / iSTAR, CCOTZ 37-bit) — a dual-frequency 125 kHz + 13.56 MHz 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 Software House (C-CURE / iSTAR, CCOTZ 37-bit) works

The Software House (C-CURE / iSTAR, CCOTZ 37-bit) 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 CCOTZ proprietary 37-bit credential for C-CURE 9000 / iSTAR; RM-series readers also embed standard HID Prox, multiCLASS and Indala. 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 Software House (C-CURE / iSTAR, CCOTZ 37-bit) by encoding the matching data structure onto a programmable T5577 / EM4305 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 Software House 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.

Software House (C-CURE / iSTAR, CCOTZ 37-bit) — common questions

Is this a genuine Software House card or a compatible one?

It is an independently manufactured compatible credential — engineered to the same specification as the Software House (C-CURE / iSTAR, CCOTZ 37-bit) so it reads identically on your existing readers, but it is not an Software House-branded product. Security ID Systems is independent and not affiliated with Software House; your access-control panel accepts the credential exactly the same way.

What chip is the compatible Software House (C-CURE / iSTAR, CCOTZ 37-bit) encoded on?

It is encoded on a T5577 / EM4305 programmable chip. That platform carries the original 125 kHz LF + 13.56 MHz HF 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 Software House (C-CURE / iSTAR, CCOTZ 37-bit)?

It operates on 125 kHz LF + 13.56 MHz HF, using ccotz proprietary 37-bit credential for c-cure 9000 / istar; rm-series readers also embed standard hid prox, multiclass and indala. 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 Software House 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 Software House format hard to find?

The Software House 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.
