An official scans the QR code sticker, authenticate the record using the Government's public key and then authenticate the holder against the biodata section. Then process the record.
I wonder would a visa-like VACS OK database work as well?
That means storing info in a database. It will be accessible with the same kind of info you need to access an ETA database viz name/dob/docs number, and have the same data security as a visa record database.
However I think one of the big problems where such a VACS OK database will not work where a DOCS OK database would is that VACS OK will have to be far more accessible besides border authorities and check in agents.
