Tencent Holdings Ltd, China's largest publicly traded Internet company by market capitalization has integrated a payment function into its mobile QQ, a dominant messaging application.

Tencent said in a news release on Friday that users of mobile QQ are able to use the app as an "e-wallet" that can connect with their debit cards and their accounts on Tenpay, the e-payment arm of Tencent, to make online purchases.

Apart from allowing people to pay through mobile QQ, Tencent will also invite some of its business partners, such as Dianping.com, a group-buying site in which it has invested, to use the platform so that people will be able to directly purchase services such as restaurant-booking and taxi-booking.
