"Square" and other point of sale systems for entrepreneurs are as rumoured in the process of offering an APP for smart phones that will enable the phone to not only make payments with the customer card but the phone can take and receive payments. This is proposed by Alusra ™ Technologies. Instead of focusing on sale of hardware, they can focus on transaction fees. There is no need for a printer for the receipt. The customer can take a photo of the QR code to see the receipt online.
