Execution of credits. If a transaction is to be fully or partially refunded to the cardholder after it has been executed, the Merchant shall issue a credit to the same card. A credit may only be made with respect to a debit previously settled and the amount of the credit may not exceed the amount originally debited. With electronic execution, a credit transaction shall be initiated and a credit receipt printed out. For mPOS terminals offered by SPS, the Mer- chant is able to request a subsequent full/partial credit for a transaction in writing from the Customer Service of SPS. Once the Merchant has executed a credit, SPS is entitled to demand from the Merchant the repayment or offsetting of the transaction previously settled or reimbursed. The following applies for Alipay acceptance: Alipay allows credits to be handled which are within a period of 365 days. A credit can no longer be requested after this deadline ends. Using appro- priate customer service provisions or with a suitable written notice, the Merchant must ensure that the user is notified of the 365-day deadline at the time of the transaction.
