With the goal of reaching out to large numbers of smartphone users the new mAadhaar is released by Unique Identification Authority of India. The App features an array of Aadhaar services and a personalised section for the Aadhaar holder who can carry their Aadhaar information in form of a soft copy, instead of carrying a physical copy all the time.

The key features in mAadhaar:
Multilingual : In order to ensure the Aadhaar Services are accessible to linguistically diverse residents of India, the menu, button labels and form fields are provided in English as well as in 12 Indian languages (Hindi, Assamese, Bengali, Gujarati, Kannada, Malayalam, Marathi, Odia, Punjabi, Tamil, Telugu and Urdu). After installation the user will be prompted to select any of the preferred language. However the input fields in the forms will accept data entered in English language only. This is done to help user avoid facing the challenges of typing in regional languages (due to limitation in the mobile keyboards).

Universality: Resident with or without Aadhaar can install this App in their smart phones. However to avail personalised Aadhaar services the resident will have to register their Aadhaar Profile in the App.

Aadhaar Online Services on Mobile: The mAadhaar user can avail the featured services for themselves as well as for any other resident seeking Aadhaar or related help.
The functionalities are broadly grouped as :

Main Service Dashboard : Direct access to download Aadhaar, Order an Reprint, Address Update, Download offline eKYC, Show or Scan QR Code, Verify Aadhaar, Verify mail/email, retrieve UID/EID, Request for Address Validation Letter
