WhatsApp, the most popular smartphone app in India, is employing one of the most popular strategies that has proven to drive users in the world’s second largest market to a service: cash-back. The Meta-owned instant messaging service is running a campaign as part of which it is giving away about 11 Indian rupees, or 14 cents, up to three times to users if they send money to three different people on the app, according to users and an official company support page.

The reward comes at a time when WhatsApp is attempting to expand the reach of its mobile payments service in India. Even as WhatsApp began exploring mobile payments in India as early as 2017, regulatory pushback has prevented the popular app from aggressively expanding its payments service.
