UPI is a key digital payment system in India, with a standard limit of Rs 1,00,000 per transaction. However, banks set their own limits, such as SBI and ICICI at Rs 1,00,000 daily and PNB at Rs 50,000. New users have a Rs 5,000 daily limit initially. The RBI now allows up to Rs 5 lakh for certain payments, like to hospitals. Banks adjust limits based on risk management and technical capabilities to prevent fraud. Alternatives to UPI include direct bank transfers (NEFT, RTGS, IMPS) and mobile wallets like Paytm and Google Pay. These options ensure continued digital payment convenience even if UPI limits are restrictive.
