NXP chip cards & key fobs

Yes. We build these credentials on genuine NXP 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 NXP-branded retail products. Security ID Systems is independent and is not affiliated with, authorized by, or endorsed by NXP.

We currently document 29 NXP-based formats, 4 of which are rare formats with no equivalent sold elsewhere online. If the exact NXP-based credential you run isn't listed, send the part number or a sample — we cover more than we publish.

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.
