TechCrunch is reporting that the messaging service will use UPI, a cross-bank payment system backed by the government, to enable payments between users in the next 6 months.
That’s also an area of interest, though. WhatsApp said last year it would explore the potential to give “businesses that matter” to its users a presence on its platform. That feature was originally scheduled to ship before the end of 2016, but it is yet to go live, although WhatsApp is reportedly testing business search features with a handful of selected companies.
