Korttitarjoaja

Korttitarjoaja refers to a service provider that offers services related to payment cards, such as credit cards or debit cards. These providers can include banks, financial institutions, or specialized companies that handle the issuance, processing, or management of card transactions.

A key function of a korttitarjoaja is to facilitate secure and efficient payment processing. This involves authorizing transactions, transferring funds between merchants and cardholders, and managing the underlying infrastructure that supports these operations. They also play a role in fraud prevention and dispute resolution, ensuring the security and integrity of the payment system.

Different types of korttitarjoaja exist. Some focus on issuing cards to consumers, offering various credit limits, interest rates, and rewards programs. Others specialize in merchant services, providing businesses with the technology and support to accept card payments. Payment networks, such as Visa and Mastercard, can also be considered as a form of korttitarjoaja, as they define the rules and standards for card transactions and connect issuing banks with acquiring banks. The term can also encompass companies that offer prepaid cards or gift cards, providing alternative payment solutions.
