AadharUID

AadharUID is an all-purpose scanner app¹ for the national Indian Aadhar² health card.

AadharUID does no scanning itself, but can be used with any popular Android barcode scanner, such as QR Droid or Barcode.
also spelled Aadhaar

Callout interface

AadharUID does not do much as an app by itself, but rather provides an interface through which other applications can call it. It was built for integration with CommCare, but any Android app can access it through the following callout interface.

Making a request

Intent intent = new Intent("org.commcarehq.aadharuid.barcode.LAUNCH");
// optional: specify which field you want returned to you
// as `intent.getExtra("odk_intent_data")`.
// default value is "statusText"
intent.putExtra("odk_intent_data_field", "uid");
