A radio frequency identification (RFID) tag is used to detect the presence and identification of devices or equipment in a rack. Each device in the rack has an associated RFID tag that contains device information. The system which is implemented in the rack receives the information from the RFID tag on each device in the rack and provides the information to a central location, such as a central computer, where that information can be acted on, stored, processed, analyzed, and/or accessed by a system administrator or user, for example. The system that is implemented in the rack may continue to monitor the presence of the devices in the rack for security purposes.
