Download a UIDAI-approved app, such as mAadhaar or Aadhaar QR Scanner, from the Google Play Store or Apple App Store. Open the app and choose the option to scan a QR code.

Lionic Secure QR Code Scanner is a lightweight, no-frills security app that I like to use. It’s a great option if you frequently scan QR codes to download apps, open websites, or make payments.
