Credit cards are primarily aimed at the consumer credit business. Each card holder is typically as-signed a spending limit based on their credit rating. Purchases made throughout the month are then charged together in a single transaction, generally at the end of that month.

Debit cards can be used wherever Visa or Mastercard are accepted. They are branded with a credit card logo. Unlike credit cards, however, the funds are debited from the linked bank account more or less immediately.

What is a consumer card?

A corporate card is a card given to employees of a company. These employees then use the card to pay for travel expenses or similar business-related costs. This allows all charges to be outsourced cleanly via a cost centre, which in turn lightens the bookkeeping workload. Corporate cards or com-mercial cards are subject to higher interchange fees, which are charged to the retailer.

3D Secure is a process intended to increase the security of online credit card payments. The credit card companies each have their own process for this, such as Verified by Visa, Mastercard Identity Check, Amex Safe Key, Diners Protect Buy, JCB J-Secure. Shoppers have to enter individual PINs/TANs here, the aim of which is to reduce payment defaults due to card misuse. With implementation of the Payment Services Directive 2 (PSD2) in September 2019, the process was extended to 3DS 2.0, which requires Strong Customer Authentication (SCA).
