QR code scanner module is widely used in mobile pos terminal to complete payment.
The point of sale (POS) is the time and place where a retail transaction is completed. At the point of sale, the merchant would calculate the amount owed by the customer and indicate the amount, and may prepare an invoice for the customer (which may be a cash register printout), and indicate the options for the customer to make payment. It is also the point at which a customer makes a payment to the merchant in exchange for goods or after provision of a service. After receiving payment, the merchant may issue a receipt for the transaction, which is usually printed, but is increasingly being dispensed with or sent electronically.
To calculate the amount owed by a customer, the merchant may use any of a variety of aids available, such as weighing scales, barcode scanner, and cash registers. To make a payment, payment terminals, touch screens, and a variety of other hardware and software options are available.
Why is there more and more mobile pos terminal companies tend to use embedded barcode scanner module in their device? One of the biggest reason is that consumers tend to complete payment by smart phone app with QR code, such as Alipay and Wechat. Those mobile pos without barcode scanning function can not meet this demand, so they have to change and upgrade their solution.
