The correct name of the transaction is preauthorization.
The money on the card is only booked.
In this case the owner of the card allows our company to take off a limited amount of money from the card without the permission of the owner if it is needed. For one “preauthorization” only one “sale after authorization” can be preformed. If this happens the booked money is freed except the amount we took. After the dismissing of the preauthorization the authorization code on the warrant has to be the same as on the one that was made during the preauthorization.
At the end of the renting if everything is done correctly we do a “sale after authorization” in a value of 1 HUF, after the transaction the preauthorization is cancelled.
