Thick lines and thin lines create a code – a bit like morse code dots and dashes. Thick = 1 and thin = 0 represents a binary number eg 0011010110100

Barcodes are a method of storing information graphically so that it can be read by a laser scanner. This allows information to be scanned into a computer using the laser scanner rather than having a human enter the information manually using a keyboard. Long strings of numbers and letters can be entered into the computer with one single scan of a barcode in a fraction of a second. Therefore, the primary purpose of a barcode is to eliminate the possibility of human data entry errors and to speed up data entry.
There are dozens of types of barcodes in use throughout the world today for a variety of purposes. UPC barcodes are one of the most common types of barcodes. The UPC code is the 12-digit numerical codes used on retail products in North America. Then there is the EAN barcode, which is the 13-digit barcode used on retail products throughout the rest of the world. There are PostNet barcodes used on U.S. Mail, SCC and SSCC codes used on product shipments, Code 39 and Code 128 used for a variety of purposes such as inventory tagging, and many more.
Hope this helps!
