You can top up your PayCenter account simply by transfer. Either from your own second account or from another person, e.g. through your employer for wage and salary payments. You can find the account details (IBAN, BIC) in your personal Payment Portal. You can also send money to your account by cash deposit, but since PayCenter does not run its own branches, this is only possible from external banks. A cash deposit may therefore be associated with additional costs. Please contact the counter of the relevant bank for this.
