aCheck is a document verification service. It's used as alongside other checks to establish if documents present as expected.

Users send original data to our secure API. We create a unique QR code and an accompanying web page. Users include the QR code alongside the original data in their document design. When the QR code is scanned, an accompanying web page is displayed. A comparison can rapidly be made between the document and webpage highlighting data differences.

**IMPORTANT aCheck does not offer absolute certainty of document originality.**
