Unified Payments Interface (UPI) transactions saw a 7 per cent drop in volume to 15.48 billion and an 8 per cent fall in value to Rs 21.55 trillion in November compared with the previous month, according to data from the National Payments Corporation of India (NPCI). In October, they touched an all-time high, driven by festive sales. In October, UPI recorded 16.58 billion transactions worth Rs 23.5 trillion, the highest since the digital system became operational in April 2016. In September, volume was seen at 15.04 billion, and value at Rs 20.64 trillion. The October transactions were up due to a rise in person-to-merchant transactions (for buying goods or services) during the festive season, which came down in November.
