The PIN number of an EC card or credit card permits cashless payments. For this reason, secrecy is a crucial factor.
The safest way is the transfer of information via post. Therefore, it must be ensured that this information is not viewed by unauthorised persons.
Witte safemark® provides a wide range of PIN/PUK labels to guarantee PIN number protection.
We would be pleased to advise you!
