If youíre looking to add QR Code and Data Matrix scanning capabilities to the stock iOS Camera application, then a new jailbreak tweak called Decode Camera
by iOS developer ioshack may be worth looking into.
Just recently we showed you NativeQR
, but Decode Camera is just a little bit different in terms of feature list and usage. Notably, Decode Camera doesn't come with the Contacts QR Code sharing feature, but on the flip side, Decode Camera has a nicer interface than NativeQR and the ability to make a noise sound when the QR Code is successfully recognized, as well as scan Data Matrixes. In the end, the tweak that does what the user wants will be right for the user, and every user is different, so we will let you choose the tweak that's better for you!
Decode Camera adds two options to the menu in the Camera application: a way to enable Data Matrix scanning, and a way to enable QR Code scanning. When you enable one of the features, such as the QR Code feature, the Camera will immediately begin searching for QR Codes. When it finds one, you will hear a beep, and then the switch will turn back off. You will then get a prompt asking if you want to close the prompt or do something with the data that was collected, such as open the link in the example above.
Decode Camera adds a preferences pane to the Settings application where you can enable or disable the beeping noise that happens when your iOS device successfully detects a code:
The tweak has the advantage of being a part of the Camera application, so itís easily accessed from the lock screenís Camera Grabber unlike QR Code reading applications in the App Store. It also makes for a more centralized experience so you donít feel like youíre downloading multiple applications just to use the Camera.
If you would like to give Decode Camera a shot, it's available in Cydia's BigBoss repository for just $1.50. The tweak works with iOS 5 and later.
