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