You must choose the right payment processor if you own a business that takes debit and credit cards online. Online payment processors take care of all the difficult tasks, from capturing sales to sending you a bill statement and collaborating with banks to make sure you get paid.
Payment gateways or PoS terminals are used when a customer buys something from your site or in-store. The gateway encrypts data to ensure its security and transmits it to the payment processor, who then sends it to the card network of the customer. The card network then checks with the customer’s bank to determine if there is enough money in the account to cover the item. If the bank accepts the purchase, the card issuer will transfer funds from their account to the bank of the merchant. The payment processor will relay this response back to the merchant’s website or PoS terminal and notify the customer that the transaction was successful.
When selecting a processor be sure to consider factors like security, user-friendliness, as well as compatibility with existing systems. Choose a processor that offers APIs and plugins to seamlessly integrate with your ecommerce platform or the POS system. Also, you should consider the checkout experience for your customers, as well as the reporting and transaction management options for your team. Also, ensure that you know the terms of your contract and how easy it is to switch suppliers in the future.
