UPC-E 符号体系由八位构成。 第一位不是 0 就是 1,后面的六位是数据,最后一位是校验位。 使用数字系统选项可以指定第一个字符是 0 还是 1。
指定正确的字符数
Typically, you supply the six middle characters of a UPC-E barcode, and BarTender automatically adds the number system digit to the beginning, computes the check digit, and then adds the check digit to the end. If you supply more than six characters, BarTender might delete the extra characters, and if you supply fewer than six, BarTender will add enough trailing zeros to bring the total number of data characters up to six.
