The taxi app Kuaidi, which is venture backed by Alibaba, now supports Alibaba’s payment solution Alipay in 40 Chinese cities, covering more than 400,000 taxi drivers, according to Alipay. The payment process with the latest version of Kuaidi has been improved that customers only need to type in taxi fares. Drivers who don’t have Kuaidi app in their smartphones can also take Alipay payments through QRcodes, if customers’ phones have Alipay Wallet app. Alipay Wallet itself will soon have a taxi booking feature, the company disclosed. Didi is also subsidizing both drivers and customers with 10 yuan for each transaction.
