The Unified Payments Interface (UPI) records over 700 million daily transactions for six consecutive days in December, with the first five days exceeding Rs 1 lakh crore in transaction value, a significant milestone. This achievement surpasses previous monthly highs, reflecting increased consumer activity following salary payments. With UPI accounting for 85% of India's digital transactions, industry experts predict it is on track to reach a billion transactions per day by next year, heralding further growth in the fintech sector.
