Application for reading the numbers from a scratch card in android (like a bar code reader)
<p>I want to create an application for android that is similar to a bar code reader app. but instead of reading the code it will read a 16 digit long number from a scratch card.</p>

<p>(The scratch card number will be used for reloading the credit in the mobile.)The app will open the camera, read the 16 digit long number and will put that number in the dialer.</p>

<p>Can any one help about from where should i start and how it can be achieved...?</p>
