Online payment processing refers to the technology and systems that allow businesses to accept payments over the internet. This process typically involves a customer entering their payment information, which is then securely transmitted to a payment processor. The payment processor verifies the transaction and communicates with the customer's bank to ensure funds are available. Once the transaction is approved, the payment processor sends a confirmation back to the business, completing the sale. Common methods of online payment processing include credit cards, digital wallets, and bank transfers. This system enables businesses to operate efficiently and provides customers with a convenient way to make purchases online.
