Bar code overview and development history

  Bar code is a combination of lines and blank symbols according to certain coding rules, used to represent a certain number of letters, numbers and other data. For identification, a barcode reader is used to scan and obtain a set of reflected light signals. The signal is converted into a set of electronic signals corresponding to lines and blanks, decoded and restored to the corresponding text numbers, and then transmitted to the computer. Bar code recognition technology has been quite mature, its reading error rate is about one in a million, the first reading rate is greater than 98%. It is an automatic data collection technology with high reliability, fast input, high accuracy, low cost and wide application.   

There are about 225 kinds of 1D barcodes in the world, and each 1D barcode has its own set of coding specifications, which stipulate that each letter (which may be text or number or text digit) consists of several lines (Bar) and several blanks (Space) and the arrangement of letters. Generally popular 1D barcodes are 39 codes, EAN codes, UPC codes, 128 codes, specifically for booklet management ISBN, ISSN, etc.
