Blank Programmable Cards

Nedap Compatible Proximity Card

125 kHz LF

A factory-fresh, rewritable Nedap (Magna / NeXS / TRANSIT / uPASS) — the programmable blank our compatible 125 kHz proximity credentials are encoded onto, supplied loose or pre-encoded in bulk. Order single spares or bulk quantities at a fraction of OEM list pricing.

How the compatible Nedap (Magna / NeXS / TRANSIT / uPASS) works

The Nedap (Magna / NeXS / TRANSIT / uPASS) 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 128-bit ASK/Manchester structure (subtype + customer/ID fields, ~64-bit repeating ASK); Nedap XS tags carry a mandatory customer code the reader filters on. 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.

As a programmable blank, the Nedap (Magna / NeXS / TRANSIT / uPASS) is the raw material the rest of the catalogue is built on. We supply it factory-fresh and rewritable on the T5577 / EM4305 platform, so you — or we — can encode it to emulate the proximity format your readers expect. It is the backbone of every 125 kHz compatible credential we ship.

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

Nedap (Magna / NeXS / TRANSIT / uPASS) — common questions

Is this a genuine Nedap Identification Systems card or a compatible one?

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

What chip is the compatible Nedap (Magna / NeXS / TRANSIT / uPASS) encoded on?

It is encoded on a T5577 / EM4305 programmable chip. That platform carries 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 Nedap (Magna / NeXS / TRANSIT / uPASS)?

It operates on 125 kHz LF, using 128-bit ask/manchester structure (subtype + customer/id fields, ~64-bit repeating ask); nedap xs tags carry a mandatory customer code the reader filters on. 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 Nedap 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.

Why is the Nedap Identification Systems format hard to find?

The Nedap Identification Systems 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.
