With the Barcode Scanner application for our LG Optimus ONE, ME, black, 2X, CHIC and GT540 or any other Android device, we can read bar codes in 2D and the QR codes.
As you may have noticed, QR codes are used enough to download some applications, and as here we’re going to use it much, it is recommended that you download and install it. In this video we watch how it works
Also we can generate QR codes of our contacts to another people can scan the code and add the contact. Press the Menu> Show bar code when we’re viewing a contact in our address book.
This application must be in all HTC Android, so we wanted to start with this application .
Barcode Scanner is available free in Android Market.
