AadharUID

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

1. AadharUID does no scanning itself, but can be used with any popular Android barcode scanner, such as QR Droid or Barcode.
2. 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");

Receiving a response

odk_intent_bundle

intent.getBundleExtra("odk_intent_bundle")

This bundle will contain the following fields:

• Special values:
  • statusCode either "0" (success) or "1" (parse error)
  • statusText either "✓" (success) or "✗" (any failure)
  • rawString the raw string represented by the QR Code or barcode
• Values straight from the Aadhar barcode
  • co
  • dist
  • dob normalized to YYYY-MM-DD
  • dobGuess dob if provided or else yob-06-01
  • gender normalized to M or F
  • house
  • lm
  • loc
  • name
  • pc
  • po
  • state
  • street
  • subdist
  • uid
  • vtc
  • yob

Some Aadhar cards use a 2D barcode. On these cards, only the uid is encoded; the rest of the values will be "".

odk_intent_data

intent.getStringExtra("odk_intent_data")

This value will be set to whatever field was requested through the odk_intent_data_field extra. For example, if odk_intent_data_field was set to "uid" in the request intent, then the odk_intent_data extra will be set to the uid value. By default it is set to statusText.
