摘要：
A call button attached to a Radio Frequency Identification (RFID) tag may be activated to send an alert to appropriate personnel. Direct current voltage is received at an input of a RFID tag. Responsive to a query of an RFID reader, the RFID tag detects a state of the call button based on a level of the direct current voltage present at the input of the RFID tag. The RFID tag sends the detected state of the call button to the reader. A signal is sent from a server based on a reported state of the call button.
