Our payment system defers small payments and collects them into bundles. We charge at the moment of purchase only the first time. Afterwards we add payments into the bundle until it reaches a predefined limit or the end of the month, whichever comes first.
The initial limit is €3. Afterwards we increase this limit depending on your purchase frequency and amount spent. The maximum limit is €10.
Each time your card is charged we send an invoice to the email address that you used to sign up for the Trafi app. The invoice contains a detailed break-down of which purchases you were charged for.
