Which UPI app is fastest?

BHIM (Bharat Interface for Money) is considered one of the fastest and most reliable UPI apps as it is developed directly by the National Payments Corporation of India (NPCI). Being the official app, it offers a streamlined interface that connects directly to the UPI infrastructure for high transaction success rates. Additionally, using the UPI Lite feature within the app allows for near-instant small-value transactions without needing a PIN, further increasing speed and reducing bank server delays for daily payments.
