Facebook has a launched a new trial that would allow users to pay for products through the site in a few clicks, using a system called Qwick. In the Asia Pacific region, retailers selling products through Facebook is fairly common, with items sold over social media in Thailand worth around 500 million US dollars a year. Users began to notice the service last week, when the feature appeared on some high profile retailers' pages across the site. It is similar to the peer-to-peer money transfers that were enabled in the US and UK recently and has been said to appear to be more about increasing user engagement rather than increasing revenue. However, tough competition does already exist in the region, where Line's payment service and shopping app are already fully implemented.
