Boycott SOPA is a new Google Android app that lets you scan a product’s barcode and see if it is from a manufacturer that has a pro SOPA stance.
The database is fairly limited right now and information might be outdated. But it still gives you an idea.
The developers spoke about the app:
There are currently over 800 brands/companies on our list. The list currently being used by the application is available on our website listed below.
This application will help you identify goods of companies which according to publically available sources appear to have been supporting SOPA as of approx. January 5th 2011, but the list will be updated as we go.
It is intended as an aid to identifying such products but should not be relied upon. You should carry out your own check in case of any product this app indicates is a product of a company supporting SOPA is not.
