Examples

To encode the data "12345678" without the check digit manually, simply key in "{,BXn}" and select the FontCodeI2of5H3.ttf font. The output is as follows :



To encode the data "1234567" with the check digit manually, simply key in "{,BXf}" and select the FontCodeI2of5H3.ttf font. The output is as follows :



The "f" is the check digit. It represents the value 70 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.

Data1234567
Starting from the last digit, multiply by 3 followed by 1.
*3*1*3*1*3*1*3
Sum : (1*3) + (2*1) + (3*3) + (4*1) + (5*3) + (6*1) + (7*3) = 60
If the Sum Mod 10 is 0, the result is 0. Otherwise the result is 10 - (Sum Modulo 10)
Modulo 10 :(60 % 10) = 0
Data to be encoded123457 (and 0 as the Check Digit)
Mapping12 = ',' , 34 = 'B' , 56 = 'X', 70 = 'f'

The characters "{,BXf}" can then be keyed in to the text editor with the appropriate font selected to generate a I2of5 barcode with check digit.
