Claim 8:
9. The system according to claim 1, further comprising:
a contactless passive transponder configured to communicate with a reader via an antenna by using a carrier signal, the contactless passive transponder including the integrated circuit having two antenna terminals connected to the antenna;
wherein the integrated circuit further includes a comparison circuit configured to compare the voltage of said first electrode with said threshold; and
a processing circuit configured to: command a charging of the first capacitor in response to a first command from the reader; command a charging of the second capacitor in response to a second command from the reader; activate the measuring circuit in response to an activation command from the reader; and communicate a result of said comparison in response to a read command from the reader.
