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.
The Nedap Identification Systems format sits among the specialist proximity credentials most card vendors never tooled up to produce — which is why the only other source is usually the original manufacturer, at a steep premium. Supporting these hard-to-find formats is exactly what Security ID Systems specialises in. Tell us the format printed on your card, or send a sample for us to read, and we confirm compatibility before you order.
