What is barcode?

My project is related with two important elements: RFID and Barcode. So this week i would like to share with you what is barcode. 


When you purchase an item from any store, you will notice a label with thin, black lines across it, along with a variation of different numbers. This label is then scanned by the cashier, and the item's description and price automatically come up. 

The word for this is called a barcode, and it is used to read data and information based upon the widths of those small black lines. The barcode has many uses, although most of us think of them as simply a way to price items in the grocery or department store. 

Barcodes are becoming more and more common in just about every facet of consumer life.



The technical definition for a barcode is a machine readable form of information on a scannable, visual surface. They are also often known as UPC codes.

The barcode is read by using a special scanner that reads the information directly off of it. The information is then transmitted into a database where it can be logged and tracked. Merchandisers and other companies must pay an annual fee to an organization called The UCC, or Uniform Code Council, who then generates special barcodes specific to that particular company.

Each number on a barcode has a special meaning, and often these numbers are added, multiplied, and divided in some formula that gives them each their own special individuality. Barcodes are very useful for maintaining accurate information about inventory, pricing, and other important business-related data.
