KvitkaCard is a digital, anonymous and public card: all data (unique number, points balance, top-up and spending statistics) is available via the link and is not linked to a specific person.
Opening a card is free, does not require personal data and is not limited in quantity.
The link to your card is your only way to access it, so be sure to save it for future use. If you lose it, you can easily create a new card.
