Modern payment processors allow even small businesses to accept payments made through a mobile app or mobile card. It can be used by anyone, whether you're running an online or brick-and-mortar shop. To get started, the first thing you need is a reliable credit card processing system. Ask your agent about upgrading the plan so you can offer a mobile app payment option to your customers as well. Make sure you're prepared for the extra processing fees. For businesses that don't accept card payment options yet, they'll have to apply for credit card processors first. On the other hand, if you don't plan on accepting credit and debit cards but want to process mobile app payments online, opt for mobile credit card readers. These are payment processors that provide businesses access to a virtual terminal that can authorize and process mobile card payment transactions. Some of the best options in the market include PayPal, Square, and Shopify, among others.
