PIN/PUK security labels – reliably non-transparent
About the product
Security when passing on information
Secret numbers such as PINs and PUKs provide access to important data, facts and functions.
Before the sequence of numbers and/or letters reaches the intended user, it requires reliable protection. These labels conceal the information that is intended for the rightful recipient.

Secure products for sensitive industries
The security labels are often used in the telecommunication and banking industries. PIN/PUK security labels are used for sending PIN numbers for EC cards, health insurance cards and personal ID cards. The PIN/PUK security labels are also suitable for use in authorities, e.g. for passing on transaction numbers, and also in the lottery business.
We subdivide the PIN/PUK security labels into three different categories:
Scratch-Off Labels
The information is revealed by scratching off the relevant field.
Peel-Off Labels
The information is revealed by pulling off the upper label.
High Security VOID Labels
Security features can be incorporated in these labels.
Witte safemark has developed a PIN scratch label made of paper as part of its sustainability efforts: the PIN-VOID-ECO.
Of course, this solution is opaque, so that information can still be transported securely to the recipient.
Processing via dispensing machines is just as possible as with the film version. Our transparent paper material is FSC-certified and, as usual with Witte, offers a wide range of customization options.
The scratch-off label can be supplied with or without VOID function. The scratch-off area can be provided in different colors and, if desired, with a text (e.g. “Please scratch off here”).
With the paper PIN mailer, the label and the paper no longer have to be laboriously separated for waste separation, but can be disposed of together in the paper waste.
