Hereinafter, the QR code input from the camera module 121 will be described with reference to FIG.

4 is a diagram showing QR code information from a QR code and a QR code.

QR (Quick Response) codes are similar to conventional bar codes, but they are a more advanced code system than conventional bar codes in terms of usability and information. It can be used as a square irregular mark in actual billboards or memos.

The existing barcode is basically a one-dimensional structure that can only contain numerical information of up to 20 letters in horizontal arrangement. However, QR code utilizes the width and height to make a maximum of 7,089 characters, a maximum of 4,296 characters, and a maximum of 1,817 characters It is a two-dimensional structure that can record the degree of a person. Therefore, at most, only the information of a specific brand name or manufacturer can be recorded in the barcode.

However, the QR code can contain various information, so it can contain a long sentence Internet address (URL), photograph and video information, map information, and business card information. That is, when the QR code is read through the QR code reader, it is possible to access the server corresponding to the Internet address, and obtain the moving image information, the map information, and the business card information. In recent years, QR codes have become widely used as on-line and off-line as they become important public relations / marketing tools for companies.

The QR code also has an error recovery function that can restore data information even if a portion of the code is dirty or damaged. Of course, if damage / contamination is severe, restoration is impossible, but it is true that recognition rate is better than existing barcode. In addition, the shape of the code is square, so 360 degrees can be read correctly in any direction. Moreover, since it is hardly affected by background / background pictures, it can be inserted into various types of promotional / promotional materials.

The most active application of QR codes is in the advertising / public relations industry. If you can not deliver enough information due to limited space, whether it is online or offline, you can use QR code to refer to additional information on the Internet. If you read the QR code using a QR code reader application such as a smart phone or a tablet PC, you can access the product's Internet site to check additional information. It often contains detailed information such as photos and videos. In department stores and shopping malls, discount coupon information is included in the QR code so that coupons can be easily used on smartphones when purchasing products.

Referring to Fig. 4 (a), an exemplary QR code 400 is shown. The QR code can be generated in various ways, and when the QR code 400 is read as described above, URL information, map information, and moving picture information can be obtained. The QR code included in FIG. 4 (a) is an example generated QR code, but is not limited thereto.
