India's Unified Payments Interface (UPI) reached a new high in December, processing 21.63 billion transactions valued at Rs 27.97 lakh crore. This marks a rebound from November's dip, with growth attributed to increased consumer spending during the holiday season for purchases, travel, and retail. Other digital payment methods like IMPS and FASTag also saw increases, while AePS transactions declined. UPI's year-on-year growth remains strong, with transaction volumes up 29% and value up 20%.
