Authorization. Unless otherwise expressly agreed, the Merchant is obliged to obtain authorization from SPS for any form of card acceptance by means of a procedure specified by SPS. This does not apply to exceptions explicitly authorized by SPS (e.g. contactless card acceptance by means of offline transactions). The Merchant acknowledges that within the context of the authorization procedure, it can only be verified whether a card is not blocked and no limit has been exceeded. An authorization granted therefore does not confer on the Merchant any claim to the reimbursement of the transac- tion by SPS.
