Two-dimensional code scanner is an instrument for scanning two-dimensional codes of two-dimensional codes. It is commonly hand-held (barcode scanning gun that can scan PDF417, QR code and GM code two-dimensional codes) and fixed (I .e. two-dimensional code reader, desktop, non-hand-held, placed on a table or fixed in terminal equipment)
Handheld: namely two-dimensional code scanning gun. Can scan PDF417, QR code, GM code two-dimensional code bar code scanning gun,
Fixed: I .e. two-dimensional code reader, desktop, non-handheld, placed on a table or fixed in a terminal device, two-dimensional code printed on paper and two-dimensional code on the mobile phone screen can be identified, so it is widely used in electronic ticketing, electronic coupons, membership system, mobile phone two-dimensional code boarding and other fields.
Mobile phone screen two-dimensional code reading, is the two-dimensional code e-commerce application of the most ideal bar code reading device, can be widely applied to electronic membership card, electricitySub-coupons, electronic ticketing, electronic receipts and other applications of electronic vouchers.

Two-dimensional code barcode scanner composition application principle
Two-dimensional code, also known as two-dimensional bar code or two-dimensional bar code, two-dimensional bar code/two-dimensional code is to use a specific geometric figure according to a certain rule in the plane (two-dimensional direction) distribution of black and white graphics record data symbol information; In the code compilation, the concept of "0" and "1" bit stream, which constitute the internal logic foundation of the computer, is skillfully used, the use of a number of binary corresponding to the geometric shape to represent the text numerical information, through the image input device or photoelectric scanning device automatically read to achieve automatic processing of information: it has some common bar code technology: each code system has its specific character set; each character occupies a certain width; with a certain check function. At the same time, it also has the function of automatic identification of different lines of information, and processing graphics rotation changes and other characteristics. Two-dimensional bar code/two-dimensional code can express information in both horizontal and vertical directions, so it can express a large amount of information in a small area.
