The Universal Product Code was the first bar code symbology widely adopted. Its birth is usually set at April 3, 1973, when the grocery industry formally established UPC as the standard bar code symbology for product marking. Foreign interest in UPC led to the adoption of the EAN code format, similar to UPC, in December 1976. There are now five versions of UPC and two versions of EAN. The Japanese Article Numbering (JAN) code has a single version identical to one of the EAN versions with the flag characters set to ``49''. By 2005 all US retailers will have to be able to scan all EAN/UCC article numbers (8, 12, 13 and 14-digit). UPC and EAN symbols are fixed in length, can only encode numbers, and are continuous symbologies using four element widths. UPC version A symbols have 10 digits plus two overhead digits while EAN symbols have 12 digits and one overhead digit. The first overhead digit of a UPC version A symbol is a number related to the type of product while an EAN symbol uses the first two characters to designate the country of the EAN International organization issuing the number. UPC is in fact a subset of the more general EAN code. Scanners equipped to read EAN symbols can read UPC symbols as well. However, UPC scanners will not necessarily read EAN symbols. The UPC symbology was designed to make it ideal for coding products. UPC can be printed on packages using a variety of printing processes. The format allows the symbol to be scanned with any package orientation. Omnidirectional scanning allows any package orientation provided the symbol faces the scanner. The UPC format can be scanned by hand-held wands and can be printed by equipment in the store. Version A of the symbology has a First Pass Read Rate of 99% using a fixed laser scanner and has a substitution error rate of less than 1 error in 10,000 scanned symbols. Nominal X dimension is 13 mils. A magnification factor of 0.8 to 2.0 is allowed and, as a result, makes a printable range of X dimension values of 10.4 to 24 mils. In other words, the nominal size of a UPC symbol is 1.469" wide x 1.02" high. The minimum recommended size is 80% of the nominal size or 1.175" wide x .816" high. The maximum recommended size is 200% of the nominal size or 2.938" wide x 2.04" high. Larger UPC's scan better. Smaller UPC's do not scan as well or not at all.The UPC format can be printed using a variety of printing techniques because it allows for different ink spreading. The amount of ink spreading depends on printing press conditions, amount and viscosity of ink and other factors which are difficult to precisely control. The UPC symbol is decoded by measuring the distance from leading edges to leading edge of bars, trailing edge to trailing edge of bars and leading edge to leading edge of characters. Since relative distances are measured for decoding, uniform ink spread will not affect the symbol's readability. However, excessive ink spread will make the spaces very small to the point that the reader will be unable to resolve them. Since UPC is a continuous code with exacting tolerances, it is more difficult to print on any equipment except printing presses.

EAN代码〈European Article Number〉EAN条码符号是指对国际EAN协会授与的国别码2～3位数字与厂商识别代码5～4位数字组成的7位数字、商品项目代码5位数字、校验码1位数字等共计13位数字进行条码化的符号。JAN符号也包含其中。参阅：http://www.ancc.org.cn/movie/EAN%A1%A4UCCECR.ppt

是条形码。还有叫bar code

条形码好像要先去质量监督局备案，然后申请的
