Abstract
Il supporto di informazione è di tipo cartaceo avente almeno due strati accoppiati operativamente tra loro, in cui la informazione grafica viene realizzata al momento della scrittura nella interfaccia tra due strati mediante attivazione con mezzi fisici quali pressione meccanica, radiazione luminosa visibile o invisibile, energia termica.Almeno uno dei due strati è trasparente o semitrasparente per poter vedere la informazione grafica dopo la sua scrittura. Il supporto di informazione presenta caratteristiche di sicurezza anti contraffazione, modifica, cancellatura poichè le informazioni grafiche sono presenti nella interfaccia non accessibile tra gli almeno due strati.Il supporto di informazione trova particolare utilità in carte valori, assegni bancari, cambiali ed altri documenti in cui la informazione comunque registrata non deve essere alterata e/o qualsiasi tentativo di manomissione deve essere reso palese.
