barcodes are an encoding of each letter or number into a group of thin or thick lines.  The groups are then strung together (with some error control) to represent a alpha-numeric of any arbitrary lenght.  There are several different barcode encoding standards.

Hi gstalin,

Barcodes conform to several different formats. EAN13 EAN8 UPC CODABAR EAN-ISBN CODE39 and many more. Nowadays there are even two-dimensional ones. There's plenty of good web sites you can research them now you've got some key-words..

Essentially, a barcode reader is a low-power laser that scans back and forth all the time. It also has a sensor that can detect bright and dark pulses in the laser's reflection. The barcodes themselves are just encoded letters and digits (some formats have a full character set) in the form of sequences of varying width bars.
