Admittedly, a very interesting and practical idea was proposed by three young residents of Thessaloniki.
Seeing how difficult it is for people to look for a vaccination certificate in a bag or on a mobile phone every time they enter an institution, they decided to create a keychain with a QR code.
Young entrepreneurs print vaccination certificate codes on recyclable plastic, which is a simple key ring. The owner of such a thing can easily and quickly present it to the inspectors if necessary.
The idea belongs to Yannis Kukulis, Yannis Pavlovich and Athanasios Rossikopoulos-Pappas.
A group of young people, inventors of the QR code keychain, declare that they will transfer part of the proceeds from sales to competent services that carry out tree planting in areas affected by fires in Evia and Attica.
