How does a payment gateway work?
- Collection of payment information: When a customer places an order, he enters his payment details on the webshop's checkout page.
- Encryption: The payment gateway encrypts this information to ensure security.
- Authorization: The gateway sends the encrypted data to the payment processor, who authorizes the transaction with the customer's bank.
- Processing: After authorization, funds are transferred from the customer's account to the seller's account, completing the transaction.
