Universal QReader ™ is a completely free App for smartphone / tablet, which allows you to read a Digital Seal SQCode®, a Digital Stamp dedicated to the protection of documents that are typically used and checked (even off-line) on the move. The Digital Seal SQCode®, is a QrCode code containing digitally signed data and therefore cannot be falsified.
The data structure present in the Digital Seal SQCode® is expressly designed for this kind of two-dimensional codes and ready to adapt to various contexts and applications.
The data can also be encrypted, when it is necessary to ensure their confidentiality; moreover, the same cryptographic algorithms and the same secure signature devices used in a qualified signature are always signed with the same philosophy.
