Barcode Scanner Android App is great! It allows you to scan most product bar codes in 1D (UPC, EAN, etc.) and 2D formats (QR Code) to search Google for product results.

Reading QR Code on iPhone

Back to iPhone, it doesn’t come with a built-in QR code reader. But thanks to Apple’s iPhone App Store. You can already find quite a number of QR code applications. I’d like to share one of them with you first: Barcodes.

Barcodes allows you to scan barcodes (via iPhone camera) and automatically decodes them. Currently, Barcodes only support QR codes and is part of the ZXing project, which is a project initiated by Google. From what I have experienced, nearly all QR code applications on iPhone share similiar user interface. When Barcodes is launched, it’ll put you in camera mode. You can then take a snapshot on the square image of QR code and Barcodes will decode it for you.

Barcodes provides special handling for specific information. Say, the QR code is decoded as an URL. Barcodes will prompt you to open the URL in Safari. And, for email address, Barcodes will ask you if you’d like to compose a new email for that address. How about phone number? Yes, Barcodes would let you dial the phone number directly.

For all the QR codes that you have scanned, Barcodes helps you keep a scan archive for the decoded information. Barcodes also allows you to pick any photos with QR code in your camera roll for decoding. What’s next? Download Barcodes via this iTunes download link and try out QR code below!
