Conceal the big deal
Scratch panel is a security stripe applied to a card, which may conceal details such as a PIN code, winning number, discount or a prize title. These details become legible only after the special finishing foil has been removed from the card by the card owner. Scratch panel is commonly used for pre-paid telephone cards, top-up cards, internet access cards, and competition or gift cards. A co called zebra pattern – silver scratch field with black waves is used as a standard option.
