Businesses today are always looking for ways to make their workforce more efficient. With any vehicle fleet, fuel consumption is becoming a progressively greater cost to the company. And without accurate, real-time data it is very difficult to identify where they can make improvements, leaving fleet operations without the tools needed to get the most out of their resources. Different types of GPS tracking and management systems give you the tools you need to make positive changes, based on accurate and up-to-date information. The transparency offered by GPS management and tracking systems allows companies to complete more jobs per week, reduce fuel costs, track scheduled maintenance, view proof of visit and time spent on site, optimize planning, routing , reduce administration and timesheets. There are different types of tracking systems, all used for different types of companies and workers, some of them are radio frequency identification or RFID and barcodes. Each of these systems can contain information about a good or product. Additionally, companies can understand where they are wasting huge amounts of money and time and where they shouldn't be. This essay examines RFID technology and its applications in today's business world. The roots of radio frequency identification can be traced back to World War II. The British asked Watson Watt to lead a secret project, developing RFID to identify which planes were flying from the enemy and which were a country's pilots returning from a mission. They placed transmitters on every plane they owned, which received signals from radar stations on the ground and transmitted a signal that identified the plane as friendly. And RFID basically works the same way. A signal is sent that is ... middle of paper ... Radio frequency identification has been around for more than 50 years and has only recently received the necessary attention. Radio frequency identification is a technology that uses radio waves to find and track objects, including goods and services in supply chains. Walmart has put RFID on the map by using it in its stores, vehicles and supply chain. RFID technology will only improve security, convenience and inventory management, but widespread adoption in retail operations could take several years. The healthcare industry has already started to adopt RFID technology into its daily work system. They are able to use the RFID method in many different areas to save time, money and most importantly, waste. Barcodes and RFID work great together as of now, but more and more companies and organizations will start using RFID tags once cheap disposable tags are developed.
