This article focuses on the implementation of radio frequency identification technology. Radio frequency identification (RFID) is a popular technology. It can be used to manage everything from railroad locomotives to boxes of breakfast food. RFID was developed almost 60 years ago. However, its implementation awaited a host of other technical developments as well as advances in radio technology, applications software, and even business models. RFID is mainstream now for some, but implementing it is not easy. RFID is the use of radio frequency signals to identify items. RFID uses short-range radio technologies to communicate mainly digital information associated with items by using tags attached to the items. At first glance an RFID system appears simple. However, this is not true. The tag circuitry needs to operate with a minimum of voltage and current. A tag chip uses analog, digital, microwave, and memory technologies. The signals received by the tag can vary over a very short time span. The signals may be large when the tag is close to the reader antenna or when it is exposed to an environmental source of radio waves.
