A payment processor is a company or service that handles electronic payment transactions between customers, merchants, and financial institutions. It ensures that funds are securely transferred from the customer’s account to the merchant’s account during an online or in-person purchase.
When a customer makes a payment using a credit card, debit card, or digital wallet, the payment processor manages the technical and financial communication between the merchant’s bank (acquirer) and the customer’s bank (issuer). It verifies payment details, checks for sufficient funds, authorizes the transaction, and completes the settlement process.
While payment gateways focus on securely transmitting payment data, payment processors perform the actual movement of funds. In many modern solutions, both functions are integrated into a single platform for convenience.
Popular examples include Novalnet, Stripe, PayPal, Square, Worldpay, and Adyen.
