13.56 MHz HF Smart Cards

xceedid compatible proximity card

125 kHz LF C-tier format

A compatible replacement for XceedID (Allegion) generic prox — 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 XceedID (Allegion) generic prox works

The XceedID (Allegion) generic prox 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 XceedID Wiegand 26-bit + custom (40-bit RS2 variant separate). 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 XceedID (Allegion) generic prox by encoding the identical data structure onto a programmable T5577 / EM4305 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 Allegion 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.

XceedID (Allegion) generic prox — common questions

Is this a genuine Allegion card or a compatible one?

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

What chip is the compatible XceedID (Allegion) generic prox encoded on?

It is encoded on a T5577 / EM4305 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 XceedID (Allegion) generic prox?

It operates on 125 kHz LF, using xceedid wiegand 26-bit + custom (40-bit rs2 variant separate). 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 Allegion 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.
