How the compatible Suprema Xpass / BioStar (EM / Wiegand CSN) works

The Suprema Xpass / BioStar (EM / Wiegand CSN) 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 EM4100 CSN + configurable Wiegand output; reads MIFARE/DESFire/FeliCa CSN. 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.

Because the Suprema Xpass / BioStar (EM / Wiegand CSN) is a secured smart credential, it is designed so the encryption keys stay under your control. We supply compatible blank credentials built on the matching T5577 / EM4305 platform, ready for your access-control system or integrator to enrol exactly as it would credentials ordered through the original vendor's channel. You get drop-in spares and bulk stock at a fraction of OEM pricing — and because your own system writes the keys, every credential inherits your site's security.

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

Suprema Xpass / BioStar (EM / Wiegand CSN) — common questions

Is this a genuine Suprema card or a compatible one?

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

How do you supply a replacement for my secured Suprema smart card?

The Suprema Xpass / BioStar (EM / Wiegand CSN) is a secured smart credential, so the encryption keys stay under your control. We supply compatible blank credentials on the matching T5577 / EM4305 platform that your own system or integrator enrols — exactly like ordering blanks through the original vendor's channel, at a fraction of the cost. Because your system writes the keys, the credential inherits your site's security.

What frequency and format is the Suprema Xpass / BioStar (EM / Wiegand CSN)?

It operates on 125 kHz LF, using em4100 csn + configurable wiegand output; reads mifare/desfire/felica csn. 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.
