Mobile banking too followed a similar trajectory as it notched up transaction volumes of 130.9 million during the month compared to 72.3 million in the year ago period. Unified Payments Interface (UPI), touted as the mobile wallet killer at the time of its launch, shot up to 76.8 million from 0.3 as of November 2016 last year. “There is no doubt that it (note ban) has increased the level of the digital economy significantly.
