The rise of Chinese mobile payments is one of the topics that will be discussed at the Payment Solutions Summit, which is part of the four-day iGaming Super Show 2017.

Recent market data showed that China’s mobile payments sector is now worth $5.5 trillion—more than 50 times bigger than that of the United States—as more and more retailers start using online payments at their physical stores, according to Financial Times. For instance, Starbucks began accepting WeChat Pay at its China stores early this year.

And, as we all know, mobile payments is one of the hottest topics in the online gambling industry.

On Thursday, Chelsea Securities Vice President Fred Lum and Le Prevost Consultancy CEO Robin Le Prevost will hold a panel session focusing on China and its mobile payments providers, including WeChat Pay, AliPay and China UnionPay.
