Thick and tiny lines actually represent digits. Once the bar code scanner ‘reads’ them, computer program compares that number with the inventory database and retrieves the price plus makes changes in the product quantity sold.

Hi,
I assume you mean how to go about barcoding your products.
Really, you need to think about the number represented by the barcode as opposed to the bars themselves. These numbers are generally 13 digits long (12 digits numbers can be thought of as 13 digit numbers with a zero for the first number).
Small 8 digit numbers also exist, however, these are a lot harder to get hold of and cost more.
First, contact the GS1 organisation of your country. They will issue you with a ‘prefix’, which will start with the code for your country (eg 539 for Ireland).
Say you were given 539000000, then you would be able to use codes from 539000000000C to 539000000999C on your products (C is the check digit)
The procedure for books and serials (eg newspapers and magazines) are slightly different. The number is worked out frrom the ISBN or ISSN number.
You would then just have to communicate the numbers you were using to your customers.
