1. A device for use in recording incidence and duration of close contact for tracking at least one disease, the device having
embedded therein at least one circuit including:
a semiconductor processor;
a memory;
a clock;
an identifier; and
a transmitter/receiver with an antenna,
wherein the transmitter/receiver is for receiving the identifier of at least one other similar device when the device and
the at least one other similar device are in close contact, the semiconductor processor being for stamping the received identifier
with a received date and a received time, and the memory being for storing the received identifier with its received date
and time, and wherein the received identifier and its received date and time are stored in the memory for a predetermined
time of not less than an incubation time for the at least one disease.
