IntroductionBarcodes are used everywhere around us. They are used to track products until shipping, track products in a store, speed up and improve the checkout process, while allowing faster access to information. Barcodes began to be widely used in the 1970s. This marked the start of a big movement in the consumer industry, speeding up the checkout process and allowing easier inventory tracking. However, like all technologies, barcodes have been improved many times and are being replaced by better and more efficient systems (Bonsor). RFID, or radio frequency identification, is the new system that replaces the use of barcodes. RFID tags allow users to more quickly obtain information about the object identified by the RFID tag (Evans, 2012, p. 190). RFID tags are more useful and will eventually replace barcodes entirely because they allow the user to scan the item without physically touching it or optically reading anything on it. Rather than reading an identification number which is then looked up in a database, it is possible to collect information directly from the tag (Bonsor). How does it work? RFID is a technology that has been developed, updated and improved since 1970 (Bonsor). ). 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 broadcast via wireless networks, except that they generally have a shorter range (What is RFID, n.d.). There are two main types of RFID tags: active and passive. The difference between these two types is how and when they transmit the stored information. An active RFID tag is connected to a power source, middle of paper ......ete (8th ed.). Upper Saddle River, NJ: Pearson Education. Totty, M. (June 2, 2009). Business Solutions New ways to use RFID.
