Radio Frequency Identification (RFID) is used in a wireless system and has to components to it. The two components are tags and readers. The reader is a device that has multiple antennas that emit radio waves and receive the signals back to the RFID tags. Tags communicate radio waves and other messages to people nearby that can either be passive or active. Passive RFID are run by the readers and do not operate on batteries. Active RFID are powered by batteries. Readers can be mobile or mounted on walls. They can even be built into household things such as, cabinets. RFID systems use radio waves to transfer data. RFID are even used in a hospital or healthcare setting. RFID provides benefits to healthcare and hospitals for a variety of reasons. They are used for equipment tracking, inventory control, out of bed or fallen detection, and monitoring patients. It is even used to make sure the patient gets the correct medication they need and prevent the distribution of drugs people do not need or should not be having. The FDA values RFID and does not have any objections to it.
