PAC International compatibles — common questions
Are these genuine PAC International cards?
No — every credential is an independently manufactured compatible product, not an PAC International-branded one. Security ID Systems is independent and is not affiliated with, authorized by, or endorsed by PAC International. Our cards are engineered by specification to read identically on PAC International readers.
Which PAC International formats can you supply compatibles for?
We currently document 2 compatible PAC International formats, 1 of which are rare formats with no compatible sold elsewhere online. If your exact PAC International 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 PAC International 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.
