Brivo compatibles — common questions
Are these genuine Brivo cards?
No — every credential is an independently manufactured compatible product, not an Brivo-branded one. Security ID Systems is independent and is not affiliated with, authorized by, or endorsed by Brivo. Our cards are engineered by specification to read identically on Brivo readers.
Which Brivo formats can you supply compatibles for?
We currently document 3 compatible Brivo formats, 2 of which are rare formats with no compatible sold elsewhere online. If your exact Brivo 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 Brivo 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.
