You received the PIN letter about three days after you received your signature card from D-TRUST. In addition to the card PIN and transport PIN, this PIN letter also contains the Card PUK listed.
After entering an incorrect PIN three times, the card will be blocked. With the card PUK, you have the option of unlocking both the card PIN and the signature PIN.
Unlocking can be performed a maximum of ten times.
Unlocking the PINs on the old value reset. It is not possible to assign a new PIN. This means that if you have forgotten your PIN, the card can no longer be used.
