Radio Frequency Barcodes :: Technology Essays

Radio Frequency BarcodesHistoryTraditionally, companies withstand used standard paper barcodes in conjunction with information databases to steer inventory and monitor product movement. By tracking incoming and upcoming product, barcodes form an easy means of maximizing the overall efficiency of a business. Barcodes do however have certain limitations. Barcode s movening is dependent on the orientation of the barcode with the horizontal laser s massner and therefore the overall festinate of the process generates a function of the speed at which the individual can orient and then scan. This minor limitation may be a soon be resolved as Radio-Frequency appellation (RFID) technology maximizes the capability for efficient and quick product management in the form of electronic barcodes. Radio-Frequency Identification is not a new technology but has become realistic through recent advancements. Key PlayersA small smattering of companies inside and outside the United States are dev eloping this new technology. A comp either called RF-ID.Com specializes in electronic barcodes and transponders for the management of everything from automobiles to cattle, beer kegs, and packages. While another, RF Ideas Inc. has teamed up with such companies as Motorola and Microsoft to manufacture a form of proximity delirious identification or AIR ID as a form of added pledge for Windows NT systems. These companies and others have been testing RF-ID technology throughout Europe for quite slightly time in product test runs. Technology Different companies prolong a variety of products as solutions to different customer needs. The core of any RF-ID system is the Tag or Transponder which can be attached to or embedded at heart objects. (1) RF-IDs come in all shapes and sizes, from lowly glass transponder capsules to being placed in between layers of paper or plastic to form inexpensive stickers for disposable use. But all of the Radio-Frequency Identification technology reli es on the same principle, wireless communication between a RF-ID or transponder and the RF Module of a expresser. The data collected from an RF-ID can either be sent directly to a host information processing system through standard interfaces, or it can be stored in a portable indicateer and later uploaded to the computer for data processing. (1) When a transponder comes within range of a reader it uses energy collected from a RF wave that is stored in a capacitor to broadcast its own state message which is received by the reader. (1) Many of the new transponders feature read/write updating so that information can be read and uploaded on the fly.
