WhatsApp has finally started testing the digital payments feature it's been working on since early 2017. The Facebook-owned chat app is currently giving a limited number of users in India the chance to give its built-in payments feature a spin. Based on the screenshots shared by UI designer Nagender Rao Savanth‏, testers will have to verify their phone number via SMS to be able to use the government-backed Unified Payments Interface within the app. They can then choose among the pretty large list of banks available, including the State Bank of India, HDFC Bank, and ICICI Bank, which are some of the biggest in the country.
