Introduction Barcodes are used everywhere around us. They are used to track products through shipment, track products at a store and speed up and enhance the checkout process, as well as allowing faster access to information. Barcodes began to be used heavily in the 1970’s. This began a great movement in the consumer industry, speeding up the checkout process and allowing easier inventory tracking. However, just like all technologies, barcodes have been enhanced many times over and are being replaced by better, more efficient systems (Bonsor). RFID, or radio frequency identification, is the new system that is replacing the use of barcodes. RFID tags allow users to more quickly obtain information from the object that the RFID tag identifies (Evans, 2012, p. 190). RFID tags are more helpful and will eventually replace barcodes entirely because they allow the user to scan the object without physically touching or optically reading anything on it. Rather than reading an identification number that is then looked up in a database, it is possible to gather information directly from the tag (Bonsor). How It Works RFID is a technology that has been developed, updated, and enhanced since the year 1970 (Bonsor). The technology has advanced, making it more efficient, usable, and productive. RFID uses radio waves to transmit information from an RFID tag to an RFID reader. These radio waves are similar to those that are broadcast through wireless networks except are generally shorter range (What is RFID, n.d.). There are two main types of RFID tags: active and passive. The difference between these two types lies within how and when they transmit their stored information. An active RFID tag is connected to a power source, ge... ... middle of paper ... ...ete (8th ed.). Upper Saddle River, N.J.: Pearson Education. Totty, M. (2009, June 2).

  • RFID vs Barcodes

    938 Words  | 2 Pages

    Radio frequency identification (RFID) is a computerized ID innovation that uses radio recurrence waves to exchange information between an onlooker and things that have RFID gadgets, or tags, joined. The tags hold a microchip and receiving wire, and work at universally distinguished standard frequencies. Barcodes are much smaller, lighter and easier than RFID but RFID offers significant advantages. One major advantage of RFID is that the innovation doesn't oblige any observable pathway the tags could be perused as long as they are inside the range of the spectator, whereas in barcodes in order to read the barcode the barcode scanner should close around 10-15 fts. In RFID data, for example, part and serial numbers, assembling dates and support history is put away on the tags and catches which help in maintenance of equipments.

In the next few years checkouts or ‘tills’ in all retail shops will use the ICC Barcodes The goods found in supermarkets are labelled with barcodes used to identify specific items on a central database. When the good is scanned a request is sent from the checkout to this main database where the request is handled and the appropriate information returned to that terminal and the correct amount reduced from the stock of that item. The bar codes are formed of lines of different widths and as each line represents a number the resulting code is the information sent to the main computer.
