Barcodes
Barcode is the unique code that is printed on various products that we purchase from the market. Even a book that you purchase is printed with a barcode. The barcode is a set of particular lines and number and each product has its own unique code. The barcodes makes it easier to get all the information about the product or object on which it is printed. Now the shopkeepers do not have to know about the cost and features of each and every object but they can just pass the sensor machine over the bar code and all the information about the product including its manufacturing date, cats and batch number will be displayed on the computer. The barcode technology has also helped to prevent robbery case in super stores.
Now a person cannot take any product outside the shop until and unless it is swapped over by the bar code sensing machine or else an alarm will start and the customer will be arrested. The barcode facility is now used worldwide everywhere in all the shops, hospitals and other places to easily find all the information about the product. The barcode is unique code for every product. Electronic tagging also consists of a unique bar code that is mostly used to apply on animal, person or an object. There is a microchip inside the tag helping the supervisor to keep a close check on the person throughout a particular area.
