Last Updated on August 9, 2023 by Kanakkupillai

Aadhaar Card Scanner

UIDAI has introduced a new Aadhaar Card Scanner, an enhanced QR code on the e-Aadhaar containing secure and encrypted demographic details. This upgraded QR code includes the last four digits of the Aadhaar number, gender, and other relevant information, along with a photograph of the Aadhaar holder. These details are further authenticated with UIDAI’s digital signature, ensuring higher security.

As a result of this advancement, the Aadhaar QR code scanning process has become more robust and resistant to tampering. The authorities have also released a user-friendly Aadhaar QR code scanning application that is compatible with Android and iOS devices, streamlining the user experience.

What is a Secure QR Code?

A secure QR code, as described on the UIDAI website, is a visually encoded representation of the Aadhaar holder’s demographic information, complete with a photograph. UIDAI digitally signs this QR code, and its authenticity can be instantly verified by cross-referencing it with UIDAI’s digital signatures through their dedicated application.

This enhanced QR code implementation effectively identifies attempts to falsify Aadhaar information, offering a dependable method to detect discrepancies. The upgraded QR code encompasses essential data, such as Reference ID, Date of Birth, Name, Gender, Mobile Number, Email, Address, and a 2048-bit digital signature.

Obtaining and Utilizing the Secure QR Code

Acquiring the secure QR code is simple for residents seeking offline verification using their older Aadhaar card copies. Visit the official UIDAI website to obtain your Aadhaar secure QR code. You can utilize Android or iOS applications or handheld scanning devices to validate the secure QR code.

Utilizing the Secure QR Code

Here’s a step-by-step guide on effectively using the secure QR code:

  1. Install the dedicated UIDAI QR code application and proceed to scan the secure QR code using the physical scanner.
  2. Once the QR code on the Aadhaar card is digitally confirmed in the backend system, the application will display the holder’s demographic details, including the photograph.
  3. In cases where the digital signature is not verified, the scanner will indicate ‘QR Code not verified.’

Using the Aadhaar Card QR Code Scanner Application
