Congrats to Jeffrey Sharkey and his Android Scan for being one of the Android Developer Challenge winners.
Scan is an Android application that finds pricing and metadata for anything with a barcode. Just point your phone at a barcode and scan it.
Here are some key features that make Scan stand out:
- Automatic barcode recognition using onboard phone camera using ZXing
- Shows CD, DVD, or book cover along with detailed reviews from Amazon.com
- Searches over a dozen stores, both online and brick+mortar
Highlights brick+mortar stores that are nearby, with option to call the store or get directions
- Links to online storefronts to buy online from the phone
- Tracklisting for CDs, along with option to play sample tracks right on phone
- For books, searches local libraries to see if they have a copy
