Fake? Forged? Altered? Do you know? GBG IDscan does. Put simply, GBG IDscan takes a snapshot of ID documentation and checks it’s authenticity. Within seconds. But the advanced technology behind it is complex. It reads, extracts and authenticates a multitude of documents - including passports, visas, ID cards, driving licences and work permits. It automatically validates documents using advanced mathematical algorithms, colour wave technology and our proprietary library of document images. And our latest, ground-breaking innovation in mobile technology means we can validate, extract data and inspect documents direct from smartphones and tablet computers.
