Read QR codes with Apple iPhone 3GS
How to read QR codes on an Apple iPhone 3GS?
First of all, you must be clear that it is a QR code. QR codes are codes that contain information that can be read by a camera, QR codes are two-dimensional, that is, it is necessary for the Apple iPhone 3GS camera to read both the width and the height of the QR code and can contain more information than a barcode (one-dimensional).
QR codes are often used to open a web address from a mobile device such as the Apple iPhone 3GS using its 3.15 MP| f/2.8| autofocus| camera or if used with a specific application, it can offer information about a product, service or serve to authenticate a user.
In the iPhone 3GS you can read or scan QR codes without having to download any application since the code reader is included in the software of the camera.
