Create your QRCodes and control your supply chain
Empower each actor with time-stamped signatures with probative value
ValidQR is a Validity solution
Validity relies on Blockchain technology
The signature is stored on the blockchain, and is therefore not centralized, for maximum security.
It is impossible for anyone to modify the signature once stored on the blockchain.
Each insertion of a signature is accompanied by a UTC timestamp, directly supported by the blockchain.
Access to the signature can be done independently of the Validity service. It is thus very easy to carry out an audit.
