一．了解一下CODE93的发展:    

1.Code 93於1982年,基於code 39之上而設計.    

2.Code93比Code39能夠編碼更大的字符集,並且擁有更高的數據容量.    

3.Code 93設計來編碼字母和數字混合信息.    

4.Code 93需要兩個校驗碼.

二．CODE93的组成部分    

1.所能表示的数据范围:      

字母:A-Z      

数据:0-9    

符号:空格、.  、%  、 contentnbsp; 、+  、–  、/    

控制码: contentnbsp; 、+  、–  、/    

起讫码: START : "101011110";  STOP  = "1010111101"

三．CODE93的特点   

 1.可用控制码与其它与其他字母或符号组合可变成FULL ASSIC II字母   

 2.有二个检查码”C”和”K”,扫码器读取时并不输出,只在扫码器内部检查.    

3.检验码的计算方法:      

 a.先检查出资料对应的码值      

 b.检查码C从资料的最右边一位开始,用1-20的顺序排列,若超过20位,则从头开始    

c.检查码K从资料的C位开始,用1-15的顺序排列,若超过15位则从头开始.

1*3+2*9+3*38+4*14+5*13+6*24+7*12=484 C=484÷47=14 则C=14=E(对应值) K的值的计算同C

四．条形码的基本组成
