Mobile payments are an alternative form of payment available to business owners and consumers, in which portable devices serve as the purchase method. Traditionally, mobile payments are made via smartphone, personal data recorders and/or tablets. Point of sales (POS) transactions that fall under the mobile payment banner may include text message, photo, app or barcode. The barcode method requires a special scanner that retailers use at checkout, which is usually on the same POS system used for credit and debit card payments. Several mobile device distributors have their own mobile payment programs, such as Apple Pay, Samsung Pay and Android Pay. The same goes for e-commerce retailers, like Amazon.
