SignMe allows the issuance of cards with long-term validity that enables the beneficiary to use them to enter, exit and move in the interior. The subscriber’s photo is recorded on the system and can be printed on the electronic card. The card owner’s actions are linked to the surveillance cameras, as well as monitoring screens that display automatically a comparison between the subscriber’s picture during entry and exit and the subscriber’s image recorded on the system. This is to ensure that the user of the card is the same owner and owner of the image printed on the card and not another person.
