WhatsApp Payments For All Indian Users.

Facebook Inc. is set to offer its WhatsApp payment services to the whole of India as early as next week in an attempt to win market share, even though its partners aren't all ready, said people familiar with the matter.

The messaging app will partner HDFC Bank Ltd., ICICI Bank Ltd. and Axis Bank Ltd. to process the transfers, and State Bank of India will join once it has the necessary systems in place, the people said. Facebook was aiming for a full rollout with four partners but decided to go ahead with just three as its rivals were racing ahead, the people said, asking not to be named as the information isn't public.

The entry of WhatsApp into India's payments space has been likened to WeChat, which reshaped payments in China when it expanded beyond messaging. The pilot version of WhatsApp Pay -- started with 1 million users in February -- received rave reviews, threatening the market share of incumbents Google Tez and Alibaba-backed Paytm, which lack the benefits of a social network.
