The online payment transactions of Kuaidi, a major taxi application, reached almost 13 billion yuan, roughly 2 billion US dollars, this year.

Backed by China’s e-commerce giant Alibaba Group, the company introduced Alipay Wallet, a mobile payment platform, last December. Almost 73 percent of the service’s users now use Alipay Wallet to pay their fares, up significantly from less than 10 percent last December.

Four major Chinese cities including Shanghai and Beijing contributed almost half of the service’s online payment volume.

There are currently more than 100 million users and almost one and a half million drivers using the service across 360 Chinese cities.

online payment transaction 通过网络支付完成的交易 作为短语，online transaction（网上交易）更常用一些，之所以要加一个payment，是为了强调该交易在网上完成支付。如果不加，理论上online transaction可以包括线上交易、线下付款的情形。
