Nfc tags and cards checker from Cryptostamped. App allows you to read the contents of nfc tags. Only with this scanner, the nfc tags that we issue and write, can be checked for authenticity. Upon successful completion of the validation, the user sees a green shield that allows you to follow the link that is written on the label. If a non-original nfc tag is detected, a warning image appears in red and the ability to open the contents of the nfc tag is blocked. Users can register and maintain personalized scan history or collect their nfc tags.
