Mobile payments may make a trillion-dollar industry in the very near future. This may be why OnePlus has decided to jump into this market now with its own take on such a service. It may lead to direct competition with other companies such as Google, Apple and Samsung as it expands. For now, however, this new platform only works in China.
This move does put it in Xiaomi's crosshairs, though, as this OEM has had its own Mi Pay service for years. It may be a mark of OnePlus' success and increasing brand-recognition that it feels it can do the same now. This facility is accessed via a new update to HydrogenOS, the Chinese-market version of the global OxygenOS Android skin.
As with other similar platforms, it allows the user to tap-and-pay for various goods and services, public transport included. It also stores payment cards and can use QR codes. OnePlus Pay is only available to users of its most recent 7T or 7T Pro flagships at present. This suggests it could also be on certain units of their upcoming successors, which are rumored to launch in April 2020.
