Pre-authorization is a temporary hold of a fixed amount. When starting a ride in the TIER app, our system will reserve this amount to check the validity of your payment method to later pay for the ride. The pre-authorization amount will be settled when the ride is ended according to the ride cost. 

-If your ride cost is less than the pre-authorization, we will use it to cover the cost of your ride and then refund you the difference - so that you in the end only pay for the cost of your ride. 

Let's take an example; if the pre-authorization is 5 € and your ride amount is 2 €, we will refund you 3 €.

-If your ride cost is equal to the pre-authorization amount, we will use the pre-authorization to cover the ride cost. 

-If your ride cost is higher than the pre-authorization amount, we will reverse the pre-authorization transaction, it will drop off the statement entirely, then we will charge the cost of your ride. 

Let's take an example; if the pre-authorization is 5 € and your ride amount is 10 €, the 5 €  pre-authorization will be reversed then we will charge the cost of the ride 10 - so that you at the end only pay for the cost of your ride. 

The pre-authorization amount will be setteled as soon as the ride ends. it might take 7-14 working days to reflect on the bank statment, this depends completely on your payment provider.
