FalconEyeZ is an Android app that will let users create and read barcodes. The app also reads ID/driver's license and alerts if the ID holder is a minor.  This is very useful to businesses that sell age restricted products.  The app also allows the user of this app to store offenders in a blacklist in the phone. In the future that person would be flagged upon the scanning of their ID so the user of this app can take appropriate action. When storing private information, user should comply with all local privacy laws.
