Industrial 2 of 5 Barcode

This is a non interleaved and numeric only barcode that was developed in the 70's. It consists of 2 thick bars and 3 thin bars out of a total of 5 bars thus giving the name 2 of 5. It was a popular barcode in the past and was the standard in many industries. However due to its low density, it is being replaced by other barcodes like Interleaved 2 of 5. Nevertheless, this barcode can still be found in many warehouses.

To encode the data "12345678" without the check digit manually, simply key in "[12345678]" and select the FontCodeINT2of5H3.ttf font. The output is as follows :

To encode the data "1234567" with the check digit manually, simply key in "[12345670]" and select the FontCodeINT2of5H3.ttf font. The output is as follows :

The "0" 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, multiply by 3 followed by 1.
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 Mod 10)
Modulo 10 :(60 % 10) = 0 (This is the Check Digit)
Data to be encoded123457 and 0 as the Check Digit

Adding the start character '[' and stop character ']', the characters "[12345670]" can then be keyed in to the text editor to generate an Industrial 2of5 barcode.
