Guardall compatibles — common questions
Are these genuine Guardall cards?
No — every credential is an independently manufactured compatible product, not an Guardall-branded one. Security ID Systems is independent and is not affiliated with, authorized by, or endorsed by Guardall. Our cards are engineered by specification to read identically on Guardall readers.
Which Guardall formats can you supply compatibles for?
We currently document 2 compatible Guardall formats, 2 of which are rare formats with no compatible sold elsewhere online. If your exact Guardall 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 Guardall 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.
