maksuyhdyskäytävään

Maksuyhdyskäytävä, also known as a payment gateway, is a service that authorizes credit card or other online payments for businesses. It acts as an intermediary between the customer's bank, the merchant's bank, and the payment processor. When a customer makes a purchase online, the payment gateway securely transmits the transaction details to the relevant financial institutions.

The process typically involves several steps. First, the customer enters their payment information on the merchant's website, which is then encrypted by the payment gateway. This encrypted data is sent to the payment processor, which forwards it to the issuing bank (the customer's bank). The issuing bank verifies the funds and authorizes or declines the transaction. The authorization response is sent back through the payment processor to the payment gateway, and finally to the merchant's website, informing them of the transaction's success or failure.

Payment gateways are crucial for e-commerce businesses, enabling them to accept a wide range of payment methods securely. They help protect both the customer and the merchant from fraud by employing security measures like encryption and tokenization. Various payment gateways exist, offering different features, pricing models, and integration options to suit diverse business needs.
