Standard Code: the bar code composed of 13 digits is called standard code.
the size of standard code is 37.29mm × 26.26mm.
the amplification factor ranges from 0.80 to 2.00 with an interval of 0.05.
.
the 13 digit composition of the standard code can be divided into two situations:
first, the 690.
691 bar code is composed of 7 digits (country code + manufacturer code), 5 digits commodity code and 1 digit check code Second: for the barcode beginning with 692.
it consists of 8 digits (country code + manufacturer code), 4 digits commodity code and 1 digit check code<
shortened code: the bar code composed of 8 digits is called shortened code.
only when the size of standard code exceeds 25% of the total printing area, the shortened code can be declared.
.
the shortened code size is 26.73mm × The amplification factor ranges from 0.80 to 2.00 with an interval of 0.05.
.
the 8-digit shortened code consists of 7-digit commodity code and 1-digit check code.
.

the 69838 corresponding to the barcode represents the manufacturer's code, which is applied by the manufacturer and allocated by the country<
9-12 digits: a total of 4 digits.
the 0001 corresponding to the barcode represents the product code of the factory, which is determined by the manufacturer itself the 3 corresponding to the barcode is the check code, which is calculated from the first 12 digits according to a certain algorithm.
