Genuine Infineon chip technology
Infineon chip cards & key fobs
The major lock and access-control brands build their credentials on Infineon chips — and so do we. Security ID Systems supplies cards, key fobs and credentials using genuine Infineon silicon, encoded by specification for the system you run, at a fraction of OEM pricing. We are independent and not affiliated with Infineon.

Infineon chip cards — common questions
Do you use genuine Infineon chips?
Yes. We build these credentials on genuine Infineon silicon — the same chips the major lock and access-control brands use — and encode them by specification for your system. They are independently manufactured access credentials, not Infineon-branded retail products. Security ID Systems is independent and is not affiliated with, authorized by, or endorsed by Infineon.
Which Infineon-based formats can you supply?
We currently document 2 Infineon-based formats. If the exact Infineon-based credential you run isn't listed, send the part number or a sample — we cover more than we publish.
Will these work in my existing system?
Yes, when encoded correctly. We match the chip platform, data structure and — where applicable — your facility code and card-number range, so the credential presents exactly what your readers expect. We confirm compatibility before production.
