125 kHz LF Proximity Cards & Fobs

IDTECK Compatible Proximity Card

125 kHz LF

A compatible replacement for Idteck (IPC ASK[EM] / RF10 PSK) — 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 Idteck (IPC ASK[EM] / RF10 PSK) works

The Idteck (IPC ASK[EM] / RF10 PSK) is a 125 kHz low-frequency proximity credential — the band most legacy prox readers use. Its data structure is 64-bit ASK/Manchester (ASK[EM] family) for IPC cards; PSK modulation (IDC format) on RF10/IP10 readers; outputs 26-bit or 34-bit Wiegand. 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 Idteck (IPC ASK[EM] / RF10 PSK) by encoding the matching data structure onto a programmable T5577 / EM4100 / 4200 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 IDTECK 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.

Idteck (IPC ASK[EM] / RF10 PSK) — common questions

Is this a genuine IDTECK card or a compatible one?

It is an independently manufactured compatible credential — engineered to the same specification as the Idteck (IPC ASK[EM] / RF10 PSK) so it reads identically on your existing readers, but it is not an IDTECK-branded product. Security ID Systems is independent and not affiliated with IDTECK; your access-control panel accepts the credential exactly the same way.

What chip is the compatible Idteck (IPC ASK[EM] / RF10 PSK) encoded on?

It is encoded on a T5577 / EM4100 / 4200 programmable chip. That platform carries 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 Idteck (IPC ASK[EM] / RF10 PSK)?

It operates on 125 kHz LF, using 64-bit ask/manchester (ask[em] family) for ipc cards; psk modulation (idc format) on rf10/ip10 readers; outputs 26-bit or 34-bit wiegand. 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 IDTECK 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 IDTECK format hard to find?

The IDTECK 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.
