QReader is an App designed to read the electronic stamp (QR Code) that is affixed to documents digitally created, and later printed. The App, simple and intuitive, allows to perform all the controls and verifications of the document.

Paperless processes imply that the document is originated electronically and then digitally signed to ensure integrity and authenticity. Analog copies of the original document usually do not contain the digital signature cryptographic elements necessary to verify its authenticity. The electronic stamp (QR Code), placed on the hard copy, allows to go back to the original digital document.
