Abstract
Some embodiments of the inventive subject matter include a computer program product for validating a test thermoreflective mark. The computer program product can include computer usable program code configured to control a temperature regulation unit configured to govern a temperature of a thermoreflective mark. The computer usable program code can be further configured to control an electromagnetic waver emitter to present at a first temperature, a first electromagnetic wave. The computer usable program code can be further configured to record a first reflective profile. The computer usable program code can be further configured to control the electromagnetic wave emitter to present at a second temperature, a second electromagnetic wave. The computer usable program code can be further configured to record a second reflective profile. The computer usable code can be further configured to validate the thermoreflective mark based on the first reflective profile and the second reflective profile.
