Abstract
The present invention is directed to an anti-counterfeiting device comprising a first sensor configured to undergo a first user perceptible change in response to a first biologically produced stimulus that emanates directly from a biological source; and a second sensor configured to undergo a second user perceptible change in response to a second biologically produced stimulus that emanates directly from the biological source. The second biologically produced stimulus is different than the first biologically produced stimulus.
Claims22
An anti-counterfeiting device comprising:
- a first sensor configured to undergo a first user perceptible change in response to a first biologically produced stimulus that emanates directly from a biological source;
- and
- a second sensor configured to undergo a second user perceptible change in response to a second biologically produced stimulus that emanates directly from the biological source, the second biologically produced stimulus being different than the first biologically produced stimulus.
An anti-counterfeiting device comprising:
- a visible surface comprising:
- a first authentication zone configured to transition between a first state and a second state in response to a first stimulus, the transition between the first state and the second state being perceptible to a user;
- and
- a second authentication zone configured to transition between a third state and a fourth state in response to a second stimulus that is different than the first stimulus, the transition between the third state and the fourth state being perceptible to the user.

An anti-counterfeiting device comprising:
- a first substrate comprising an upper surface opposite a lower surface;
- a first sensor applied to the upper surface of the first substrate, the first sensor configured to undergo a first user perceptible change in response to a first stimulus;
- and
- a second sensor applied to the upper surface of the first substrate, the second sensor configured to undergo a second user perceptible change in response to a second stimulus.
