The UPOS app is an essential tool to help simplify and grow your business. As a merchant, simply download the UPOS app and use your smartphone to accept UPay payments from your customers. You can enjoy real-time payment processing minus the hassle of traditional card machines, additional hardware, and unnecessary bank delays. The UPOS app completely replaces the traditional card machine and transforms your smartphone, instantly, to a money accepting machine! To facilitate faster, more secure and simpler payments through the app, UPay — for the first time in Sri Lanka — has introduced dynamic QR codes. All you have to do is enter the bill amount, and a unique QR code will automatically be generated for each transaction. The customer uses the UPay app on their smartphone to scan the QR code unique to their purchase and authorizes the payment. The transaction is complete, thereafter, and the money gets transferred to your bank right away! Harness the power of UPOS, as a merchant, and be a part of the cashless society UPay is creating while growing your business. The security of your business is guaranteed through the UPOS app’s ‘Login’ and ‘Change Password’ features. Track and monitor the progress of your business with our ‘Transaction History’ and ‘Today’s Sale’ functions. Carry out transactions using the ‘Accept payments with dynamic QR’ option.
