LEGIC Prime MIM256 Card Compatible

13.56 MHz HF

A compatible replacement for LEGIC Identsystems LEGIC Prime (MIM256 / MIM1024) — 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 LEGIC Prime (MIM256 / MIM1024) works

The LEGIC Prime (MIM256 / MIM1024) is a 13.56 MHz high-frequency contactless credential read over the ISO/IEC 14443 air interface. Its data structure is LEGIC Prime proprietary RF13.56; 256B / 1KB. 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 LEGIC Prime (MIM256 / MIM1024) by encoding the matching data structure onto a programmable LEGIC Prime 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 LEGIC Identsystems 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.

LEGIC Prime (MIM256 / MIM1024) — common questions

Is this a genuine LEGIC Identsystems card or a compatible one?

It is an independently manufactured compatible credential — engineered to the same specification as the LEGIC Prime (MIM256 / MIM1024) so it reads identically on your existing readers, but it is not an LEGIC Identsystems-branded product. Security ID Systems is independent and not affiliated with LEGIC Identsystems; your access-control panel accepts the credential exactly the same way.

What chip is the compatible LEGIC Prime (MIM256 / MIM1024) encoded on?

It is encoded on a LEGIC Prime 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 LEGIC Prime (MIM256 / MIM1024)?

It operates on 13.56 MHz HF, using legic prime proprietary rf13.56; 256b / 1kb. 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 LEGIC Identsystems format hard to find?

The LEGIC Identsystems 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.
