Rosslare built an international business on pragmatic hardware: solid readers like the outdoor-rated L12C and the keypad D19, panels that speak plain Wiegand, and credentials on the widely used EM-class 125 kHz platform rather than a captive format. For facility owners this is the friendliest possible position — Rosslare-compatible replacement stock is a standard 26-bit programming job, and correctly programmed cards from any competent supplier enroll exactly like original stock. The details that matter are the usual ones: facility code, card-number range, and form factor. We program unbranded, compatible-by-specification cards and fobs to those values, verify the H10301 structure, and ship enrollment-ready — whether the system guards a Tel Aviv office, a Texas warehouse, or an apartment building anywhere between.

View compatible cardsRosslare Proximity — FAQ
What format do Rosslare proximity credentials use?
Standard 26-bit Wiegand on the EM-class 125 kHz platform is the overwhelming default, with Clock & Data output supported by some reader configurations. That openness is a deliberate feature of the Rosslare ecosystem.
Can you supply replacements for my Rosslare access cards?
Yes — send the facility code and card-number range (printed on existing cards or listed in your panel software) and we program compatible stock that enrolls like the originals. Photos of a working card are enough for us to confirm the specification first.
Are these printable for photo badges?
The ISO-body version is — standard PVC stock that runs through direct-to-card printers. Clamshells and fobs aren't printable, which is a category constraint rather than a brand one; many sites mix printable cards for staff with fobs for contractors.
Will they work on non-Rosslare readers too?
Generally yes: EM-class 26-bit credentials read on any conforming reader of the same class, which is precisely why international sites like the platform. Confirm the reader class on mixed estates and we'll match the stock to it.
