Barcode:

A bar code is a piece of Automatic Identification Technology (Auto ID) that stores real time data. It is a series of vertical bars or a graphical bar pattern which can, (depending on the width and pattern) encode numbers and letters in a format which can easily be retrieved and interpreted by a bar code reader.

Two-Dimensional Barcodes:

Two-Dimensional Bar Codes are special rectangular codes which ‘stack’ information in a manner allowing for more information storage in a smaller amount of space. These are also referred to as ‘Stacked’ Bar Codes or ‘Matrix’ Bar Codes. A standard bar code is limited to 20 to 25 characters.
