In order to read a QR code, you first need mobile phone with built-in camera. However, this alone is not enough – it is necessary that a QR reader is installed on the device – special program, designed to decipher binary codes. There are a huge variety of these programs, and their choice depends on several criteria. First of all, you need to focus on the type operating system supported by your device. Today, decoding programs have been developed for most telephone operating systems - there is special software for both Mobile MAC OS X and Windows Mobile, and for Google Android, as well as for Symbian and BlackBerry; There are also separate programs adapted for computer versions Apple, Linux and Windows.

When choosing a program that can read a QR code, you should also take into account the model of the mobile device on which it will be installed.

Once the program is installed, you can read the QR code. This process is not difficult even for those who are doing it for the first time - you just need to follow the step-by-step instructions:

2. Wait until your mobile device's camera is activated.
3. Point the camera at the QR code. At the same time, observe one of the important conditions: if binary code small, the camera should be at a distance of 15 cm from it.
4. Adjust the size and clarity of the screen image. To do this use digital zoom, which is equipped with all modern cameras in mobile devices. After adjusting the image, the QR code should be centered on the screen and have a clear outline.
5. Wait. After analyzing the QR code, the “reader” will independently give you information about its contents. If this does not happen, click on the Snapshot button to activate the scanner.
6. If nothing has changed, try again, using zoom to change the distance to the QR code being scanned.

In order to successfully decrypt a QR code, follow these rules:

• Watch the lighting.
• Ensure that your phone remains as still as possible while decoding the QR code—shaking can interfere with the scanning process.
• The mobile device must be at right angles to one side of the QR code.
• The phone must be held at the same height as the binary code.

As soon as the scanning is completed, a proposal to perform some action encrypted in the QR code will be displayed on the device screen - this can be sending sms or email, follow a link, command to make a call, save contact details, publish something in social network and so on.
