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.
