今年9月22日-25日,在广州举行的第九届中国国际中小企业博览会上,来宾收到一条彩信入场券,彩信中包含有一条与来宾手机号码、身份等一一对应的二维条码,来宾只需扫描二维码即可签到。这是我们身边手机二维码在会议、签到方面的最简捷的应用案例。二维码,又称二维条码,是用某种特定的几何图形按一定规律在平面(二维方向上)分布的黑白相间的图形记录数据符号信息的,在代码编制上巧妙地利用构成计算机内部逻辑基础的0、1比特流的概念,使用若干个与二进制相对应的几何形体来表示文字数值信息,通过图象输入设备或光电扫描设备自动识读以实现信息自动处理。二维码具有条码技术的一些共性,包括每种码制有其特定的字符集,每个字符占有一定的宽度,具有一定的校验功能等。同时还具有对不同行
On September 22-25 this year, at the 9th China International Small and Medium Enterprises Expo held in Guangzhou, guests received a MMS ticket, which contained a two-dimensional map corresponding to the guest’s mobile phone number, identity, etc. Barcode, guest can scan the QR code to sign. This is the simplest application case for the two-dimensional code of mobile phones around us in meetings and sign-ups. Two-dimensional code, also known as two-dimensional bar code, is a certain geometry according to a certain law in the plane (two-dimensional direction) distribution of black and white graphic data symbolic information, clever use of the compilation of computer code Internal logic based on the concept of 0,1 bit stream, using a number of binary corresponding geometry to represent the numerical value information, through the image input device or photoelectric scanning device automatically read in order to achieve automatic information processing. Two-dimensional code has some common bar code technology, including each code system has its own specific character set, each character occupies a certain width, with a certain verification function. Also has different lines
