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