当前,随着智能手机的快速普及,我们已经生活在二维码的“汪洋大海”中,无论在报纸、电视、互联网上,还是在咖啡厅、超市、地铁、商场里都随处可见二维码的身影。所谓二维码,是指用特定的几何图形按一定规律在平面(二维方向)进行分布的黑白相间的图形,用来记录数据符号信息。二维码起源于日本,是1994年日本Denso Wave公司为了追踪汽车零部件而设计的一种条码。二维码是比一维码更为先进的条码格式:一维 At present, with the rapid popularization of smartphones, we have lived in the “Ocean of the World” of two-dimensional code, both in newspapers, on television, on the Internet, in coffee shops, supermarkets, subways and shopping malls Dimensional code figure. The so-called two-dimensional code, refers to the use of specific geometry according to certain laws in the plane (two-dimensional direction) for the distribution of black and white graphics, used to record data symbol information. The two-dimensional code originated in Japan and was a barcode designed by Japan’s Denso Wave in 1994 to track automotive components. Two-dimensional code is more advanced than the one-dimensional bar code format: one-dimensional
