Document verification

Verify a document

Every letter and quotation issued by Infera Engine Ltd carries a QR code and a verification code. Enter the code to check that the document is genuine and still valid.

The code is printed next to the QR code at the end of the document. Scanning the QR code opens this page with the code filled in.

What the check tells you

  • Whether the code belongs to a document issued from our register, and its number, date, recipient and subject.
  • Whether it is still valid, or was cancelled, replaced by a newer version, or (for a quotation) has expired.
  • Its fingerprint: a short code calculated from the document’s full content when it was issued.

If the details differ from your copy, or the code is not found, do not rely on the document and contact us at legal@inferaengine.com.
