Card Payment Solutions is a type of payment processing service that allows businesses to accept credit and debit card payments from customers. It typically involves a payment gateway, a merchant account, and a payment processor. The payment gateway is a secure connection between the merchant and the customer's bank, allowing the customer to enter their payment information. The merchant account is a bank account that the merchant uses to receive payments from customers. The payment processor is a third-party service that processes the customer's payment information and sends it to the merchant's bank account.
