Bar Code Scanners and Inventory System
by headlymark on Mon Feb 06, 2012 12:07 pm
A bar code is simply a series of wide and narrow lines which are printed on a tag or label. Every bar on this label represents one character which a bar code reader can interpret. The reader utilizes a photo sensor which converts the code into electrical signals as it scans across the lines.
