摘要:
Methods and computer program products for locating devices having a given state by locating a device using an RFID tag associated with the device that responds to queries from an RFID tag reader independently of the state of the device, and determining the state of the device using an RFID tag associated with the device that responds selectively in dependence upon the state of the device. The invention also includes systems for locating devices having a given state. The systems comprise an RFID tag reader for locating a device by reading an RFID tag associated with the device that responds independently of the state of the device, and an RFID tag reader for determining the state of the device by reading an RFID tag associated with the device that responds selectively in dependence upon the state of the device.

Methods and computer program products for managing a device connected to a network include querying the device using the network, querying the device using a simulated RFID tag, and querying the device using a suppressible RFID tag to determine status information about the device. A system for managing a device connected to a network comprises means for monitoring status of the device using the network, for receiving status information about the device reported by a simulated RFID tag, and for receiving status information about the device reported by a suppressible RFID tag.
