E­-Commerce und E-­Payment Glossary


Credit card number or bank account number.

The acquirer and the acquiring bank take over the distribution and marketing of credit card acceptance locations. Online dealers receive an agreement on accepting credit cards as payment from this financial institution. The acquirer serves as merchant bank and settles the card payments for the merchant. Tips for online dealers: In order to allow credit card payment at the store, the merchant requires a certification according to PCI / DSS. This certification requires relatively high technical and administrative security standards. If an online shop operator cannot or does not want to undergo this test, he may opt for a payment service provider which is already PCI / DSS certified and has existing contracts for technical cooperation with one or more acquirers. The PSP acts as technical operator for the online shop.
