The second control level is carried out electronically with Prooftag professional readers.
The reading systems enable a formal authenticity check of the Bubble Tag™ by relating it to a reference database. This 3D optical verification is extremely simple, reliable and indisputable.
The Prooftag reader uses a system involving lights and algorithms to compute electronic signatures from Bubble Tags™. By connecting to the reference database, the reader compares the electronic signature to the one recorded.
Prooftag offers a range of readers adapted to the different Bubble Tag™ applications.
