FAQ

A digital autograph card is a personalised collector's item sent directly to your smartphone by the club or artist – with a personal greeting, picture and signature. Everything is done directly, without an app – but with a certificate of authenticity.

It's easy:
• Go to the club website or scan the QR code at the stadium
• Select the star and greeting
• Enter your mobile phone number
• The card will be sent directly to your smartphone via SMS/RCS

You choose a star, a greeting option and the recipient. You will then receive a preview. After purchase, you will receive the link to the card directly via SMS or RCS – no app or registration required.

The association provides images, signatures and text variants. Upon purchase, these are automatically used to create a personalised digital autograph card – with a certificate of authenticity (electronic seal).

Ja. Jede Karte ist ein Unikat – personalisiert und mit einem elektronischen Siegel versehen. Das Siegel garantiert die Echtheit und schützt vor Fälschungen.

A screenshot is possible – but only the original card with an electronic seal is considered genuine. The download link only works once and only for you.

Limitations (e.g. for special events or editions) are technically provided for and can be activated by the association.

Yes. Your data will be used exclusively for the delivery of the card – encrypted, GDPR-compliant and stored on European servers.
