All outgoing transactions should show up in your account immediately. The incoming transactions, however, can take up to 2 business days to show up.
In general, all incoming and outgoing bank transactions on your account are regulated by the SEPA framework, which is the European payment network. The SEPA framework stipulates that credit and debit transfers to and from SEPA accounts must be completed within one bank working day. This rule applies to all domestic and cross-border transfers from one SEPA account to another.
Please note that depending on the booking times of the participating banks, a bank working day can take up to two business days. The time it takes for a card transaction to appear on your bank account depends on many factors (domestic transactions, cross border, time it takes the merchant to submit transaction data for clearing and settlement, and other reasons). Most transactions will reach your account between 1 and 2 bank working days.
