Saperle says: One of the coolest things about owning a smartphone is being able to scan something in the physical world and pull up information or a link to it in the digital one. Here are a few apps to help you read or create these connections as barcodes and QR codes.
Google Goggles Not just a barcode scanner--scan the world around you and find out what you're looking at, whether it's a label or the Eiffel Tower.
Barcode Scanner What it says on the tin--scans barcodes and QR codes, anywhere, any time.
ShopSavvy Barcode Scanner Scan a barcode and instantly find out where to buy it online and locally, and read reviews of the product. You can even share it via social media, add a picture and save it to your phone.
QR Droid™ Generate QR codes, including for contacts, URLs, applications, phone numbers, location, events, text, and SMS, and also decode QRs too.
