Difference between QR CODE and BAR CODE
Code can put into one dimensional code and two dimensional code. one dimensional code is Pub code. It make up by a rule arrange strip space and quantity. this kind data coding can supply machine cognition and read, is super easy to convert binary system and decimal system. Bar code distinguish fast and high veracity great fiexiblityBut, because of the Bar code only in a single direction (horizontal) commonly show information. So the data capacity is small. Bar code often need to connect to the databases in order to get more data from the network by limited information capacity. But Bar code will loses the role within the health of not forget or database.
The QR code use Club code's information stored way extension in the two-dimensional space, need not connect a repository, it can store large data by itself, it is high thickness large capacity. QR code also have vast coding, high identification rate, difficult to abrasion. low cost etc. It could be printed in newspaper publishers and publications and periodicals, let people use mobile phone to reader it.
