Tecom Smart Card Compatible Fob

125 kHz LF

A compatible replacement for Tecom Smart — a 125 kHz proximity credential, encoded by specification to read identically on your existing readers. Order single spares or bulk quantities at a fraction of OEM list pricing.

How the compatible Tecom Smart works

The Tecom Smart is a 125 kHz low-frequency proximity credential — the band most legacy prox readers use. Its data structure is Manchester/ASK 125 kHz transponder-based smart format. 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 Tecom Smart by encoding the matching data structure onto a programmable 125 kHz transponder 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.

To order, tell us the part number or format printed on your existing Tecom card, 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.

Tecom Smart — common questions

Is this a genuine Tecom card or a compatible one?

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

What chip is the compatible Tecom Smart encoded on?

It is encoded on a 125 kHz transponder programmable chip. That platform carries the original 125 kHz LF data structure precisely, so the credential presents the same information your readers already accept.

What frequency and format is the Tecom Smart?

It operates on 125 kHz LF, using manchester/ask 125 khz transponder-based smart format. 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.

Why is the Tecom format hard to find?

The Tecom 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.
