In terms of payment method, the point-of-sale segment dominated the market in 2020, accounting for almost 52.0 percent of worldwide revenue. Point of sale systems are the systems used by retail businesses to process transactions. Using a point of sale has several advantages, including quick checkout options, a customised customer experience, and a variety of payment options. The point-of-sale payment method is used by a number of shops and restaurants to improve their customers’ payment experiences. For example, in January 2020, Grubhub, an online food ordering service, announced a partnership with ParTech Inc., a point-of-sale system provider, to integrate point-of-sale technologies into its food ordering process.
