Adel Compatible Card

13.56 MHz HF C-tier format

A compatible replacement for Adel - (covered) — a 13.56 MHz contactless smart card, 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 Adel - (covered) works

The Adel - (covered) is a 13.56 MHz high-frequency contactless credential read over the ISO/IEC 14443 air interface. Its data structure is See 'Adel A93 (Adel 1K COB)' entry. 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 Adel - (covered) by encoding the matching data structure onto a programmable 13.56 MHz smart card (ISO/IEC 14443-A) 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 Adel 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.

Adel - (covered) — common questions

Is this a genuine Adel card or a compatible one?

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

What chip is the compatible Adel - (covered) encoded on?

It is encoded on a 13.56 MHz smart card (ISO/IEC 14443-A) programmable chip. That platform carries the original 13.56 MHz HF data structure precisely, so the credential presents the same information your readers already accept.

What frequency and format is the Adel - (covered)?

It operates on 13.56 MHz HF, using see 'adel a93 (adel 1k cob)' entry. 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.
