Systems and methods for monitoring condition compliance via RFID tag
First Claim
1. A radio frequency identification (RFID) tag for monitoring condition compliance, the RFID tag comprising:
- a first chip and a second chip;
an antenna;
a switch, wherein the switch is configured to switchably connect the first chip to the antenna and the second chip to the antenna based on occurrence of a condition;
a memory device; and
a control circuit, the control circuit configured to;
write, in response to a connection between the first chip and the antenna, a first marker and an indication of a first state to the memory device;
write, in response to a connection between the second chip and the antenna, a second marker and an indication of a second state to the memory device;
determine, based on the second marker and the first marker, an amount of time in which compliance was not met; and
transmit, to an RFID reader, an indication of the amount of time in which compliance was not met.

11. A method for monitoring condition compliance using a radio frequency identification (RFID) tag, the method comprising:
-
toggling, based on occurrence and non-occurrence of a condition, a switch between a first chip of an RFID tag and a second chip of the RFID tag to switchably connect the first chip of the RFID tag to an antenna and the second chip of the RFID tag to the antenna; writing, in response to a connection between the first chip and the antenna, a first marker and an indication of a first state to a memory device of the RFID tag; writing, in response to a connection between the second chip and the antenna, a second marker and an indication of a second state to the memory device of the RFID tag; determining, based on the second marker and the first marker, an amount of time in which compliance was not met; and transmitting, to an RFID reader, an indication of the amount of time in which compliance was not met. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20)
