Person-centered activation of a radio-frequency identification tag (RFID tag)

摘要

An RFID tag (102) comprising: an antenna (106) configured to receive an interrogation signal (112); an integrated circuit (104) coupled to the antenna (106), the integrated circuit (104 ) is configured to respond to an interrogation signal (112) when the RFID tag (102) is in an active state and configured to not respond to the interrogation signal (112) when the RFID tag (102) is in an inactive state; and a skin proximity activation circuit (602) configured to establish the active state when the RFID tag (102) is in contact with the skin (604) or to establish the inactive state when the RFID tag Label (102) is not in contact with the skin (604), characterized in that the RFID tag (102) further comprises a temperature sensor (630) configured to provide a temperature value in response to a skin temperature; Activation circuit (602) is configured to establish the active state or the inactive state based on the temperature value, wherein the integrated circuit (104) is configured when the RFID tag (102) is in the active state, in response to the Interrogation signal (112) to send a response signal (114) via the antenna (106), wherein the response signal (114) includes an indication of the temperature value.
