Bar Code
translate a bar code into a computer data file.
A barcode reader (or barcode scanner) is an electronic device for reading printed barcodes.A bar code scanner reads bar codes.Bar codes contain data, typically numeric or alphanumeric data. While bar codes may all look the same to people, the data and even the "symbologies" are different. A bar code symbology is sort of like the language of the bar code, and there are many types: UPC, EAN, Code 39 (also called 3 of 9) and many others.
