DSX Access Systems (WinDSX) Credentials Compatible Cards & Fobs
The Texas titan of access software: WinDSX systems most often issue the DSX 33-bit D10202 format — 128 facility codes, nearly 17 million card numbers each — with standard 26-bit as the common alternative.
Does American Key Cards make DSX Access Systems (WinDSX) Credentials compatible cards?
Yes — American Key Cards supplies unbranded DSX Access Systems (WinDSX) Credentials compatible cards and key fobs (AKC D10202-Compatible 33-Bit Prox Card (also available in standard 26-bit)), encoded to your facility code and card-number range and ready to use on your existing DSX Access Systems readers. No hardware changes and no dealer account required.

DSX built its reputation on panels and software that integrators trust for decades, and the D10202 format grew up with it: a 33-bit structure that keeps a compact facility-code field while opening the card-number space to nearly 17 million values per code. That capacity is why large WinDSX estates almost never confront renumbering. Sites commissioned more simply run standard 26-bit instead, and both formats move through the same reader hardware — the panel's format table decides what's accepted. For the 13.56 MHz smart-credential deployments some newer DSX sites run, credentials are secured platforms ordered through those systems' own channels; for the 125 kHz world, replacement is straightforward programming. We supply unbranded, compatible-by-specification D10202 and 26-bit credentials programmed to your facility code and number range, structure-verified before shipment, ready for normal WinDSX enrollment.

What card format do DSX systems use?
Most WinDSX installations run the DSX 33-bit D10202 layout — facility codes 0–127 with card numbers up to 16,777,215 — while some sites use standard 26-bit H10301. Your WinDSX card-format configuration or a sample card identifies which; we confirm before production.
Where can I buy D10202-format prox cards?
The format is served both by OEM-channel stock and by compatible-by-specification suppliers like us. We program the 33-bit structure to your site's values directly and verify each batch on the bench, so you can order a dozen or a thousand without a dealer relationship.
Do compatible D10202 cards need special readers?
No — they read on the same 125 kHz readers your system already uses. The 33-bit structure is handled by the panel, which is already configured for it. Nothing in the hardware chain changes for replacement stock.
Our DSX site also has smart-card readers — can you supply those credentials too?
Where DSX deployments use secured 13.56 MHz smart-credential platforms, those credentials are issued through the respective platform's authorized channel, and we'll say so rather than sell you something that won't enroll. The 125 kHz D10202 and 26-bit stock is what we supply directly.
