CISA compatibles — common questions
Are these genuine CISA cards?
No — every credential is an independently manufactured compatible product, not an CISA-branded one. Security ID Systems is independent and is not affiliated with, authorized by, or endorsed by CISA. Our cards are engineered by specification to read identically on CISA readers.
Which CISA formats can you supply compatibles for?
We currently document 3 compatible CISA formats, 2 of which are rare formats with no compatible sold elsewhere online. If your exact CISA format isn't listed, send the part number or a sample — we cover more than we publish.
Will a compatible card work in my existing CISA system?
Yes, when encoded correctly. We match the frequency, 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.
