Can someone misuse my UPI QR code?

Yes, a scammer can misuse the general concept of a QR code in a UPI-related fraud, but your personal UPI QR code is inherently secure for receiving payments. UPI QR codes encrypt account data and require your confidential UPI PIN for any payment authorization. However, fraudsters often use fake QR codes that redirect to phishing websites or trick users into scanning a code to "receive" money, which actually initiates a payment to the scammer. Always verify the recipient and never scan a code to receive funds.
