• UPI transactions are free for individuals (some banks may charge for high-value transfers).
• Unlike credit cards, merchants don’t pay high fees for accepting payments.

4. Widely Accepted

• Works everywhere, from local shops to big brands.
• Used for bill payments, online shopping, investments, and more.

5. Multiple Accounts in One App

Disadvantages of UPI

1. Requires Internet Access

• UPI doesn’t work without the internet (except for USSD-based UPI on feature phones).
• Rural areas with poor connectivity may face issues.

2. Fraud & Scams

• Fake UPI links, phishing scams, and fraud calls are increasing.
• Many people fall for scams by unknowingly entering their UPI PIN.

3. Daily Transaction Limits

• Most banks have a daily limit of ₹1 lakh (some up to ₹5 lakh for special cases).
• Not ideal for high-value business transactions.

4. Dependence on Third-Party Apps

• Google Pay, PhonePe, Paytm, etc., dominate UPI, creating a risk if they face technical issues or shutdowns.
• RBI is working on a universal UPI app (UPI Lite) to reduce dependency.

5. Technical Glitches & Downtime

• Sometimes, UPI transactions fail due to bank server issues.
• Peak hours (e.g., month-end, festival sales) may cause slow processing.

Final Verdict

UPI is one of the best digital payment systems globally, offering speed, security, and ease of use. However, improving fraud protection, offline payments, and system reliability will make it even better.
