The PostFinance Card allows Swiss customers to make payments online or through mobile devices, using either the PostFinance Card or PostFinance E-Finance. It is particularly popular among younger users under 18, as credit cards are restricted to adults. Merchants can activate both payment methods via the 'eCom' solution offered by Planet.

The PostFinance Card has over 3 million cardholders in Switzerland - with an above-average number of people below the age of 18 (credit cards may only be held from the age of 18).
