Another 10 Nanyang bus lines (No 2, 9, 11, 15, 18, 23, 24, 26, 35 and 36) began allowing passengers to pay bus fares via UnionPay bank cards or QR codes on May 22, according to Nanyang Public Transportation Corporation.The new service, introduced last month, was first offered on five bus routes (No 1,3,4,6 and 21) in Nanyang, making it the first city in Henan province to bring "smart pay" to buses. There are now 429 buses driving 18 routes citywide that accept mobile payment.Residents can download the Nanyang Mashangxing or UnionPay Cloud Quick Pass app and link a bankcard to their account. QR codes generated by e-walletsof mobile apps can be scanned for payment. Upgraded ticket machines will process the fareson recognition of thecodes and then deduct the funds automatically.Or more simply, passengers can tap their UnionPay QuickPass debit or credit cards near the reading areas of compatible point-of-sale (POS) terminals to process payment.Compared with traditional cash payment, which can lead to inconveniences such as lacking the proper changeor having to wait in long queues, mobile payment ismore efficient.
