Using this Barcode ManuallyThe following table lists the characters supported by the Modified Plessy barcode.
|Data to be Encoded||Font Character to use|
To encode the data "12345678" without the check digit manually, simply key in "" and select the FontCodeINT2of5H3.ttf font. The output is as follows :
To encode the data "1234567" with the check digit manually, simply key in "" and select the FontCodeINT2of5H3.ttf font. The output is as follows :
The "4" is the check digit and its computation is illustrated in the section below.
How to compute the check digit
For example if the data "1234567" is to be encoded as a barcode. The check digit is computed as follows.
|Starting from the last digit, extract each alternate digit|
|Multiply by 2 :||1357 * 2 = 2714 (Result 1)|
|Sum the remaining alternate digits :||2 + 4 + 6 = 12 (Result 2)|
|Sum the digits from Result 1:||2 + 7 + 1 + 4 = 14 (Result 3)|
|Sum Result 2 and Result 3:||12 + 14 = 26 (Sum)|
|If Sum Mod 10 is 0, the result is 0. Otherwise the result is 10 - (Sum Mod 10)|
|Modulo 10 :||10 - (26 % 10) = 4|
|Data to be encoded||1234567 and 4 as the Check Digit|
Adding the start character '[' and stop character ']', the characters "" can then be keyed in to the text editor to generate a Modified Plessy barcode.
