Scratch Stickers
Scratch stickers are used as destructive security elements temporarily covering any printed data, number codes, PIN codes or login data. These stickers may also be used for lottery prizes, wedding lottery cards or gift vouchers.
In the manufacturing process, the sticker is pre-cut at several spots so it tears apart automatically whenever someone attempts to peel it off to look underneath – the visible irreversible damage clearly indicates the sticker was tampered with.
