1. A system configured to facilitate secure communications, the system comprising:
a light emitter;
a light detector;
a secure element configured for storage of sensitive data;
one or more processors; and
one or more hardware storage devices storing instructions that are executable by the one or more processors to configure the system to:
determine whether an authorized user operates the system;
access the sensitive data via the secure element of the system in response to the system determining that the authorized user operates the system;
cause the light emitter to emit an output light signal for detection by a second system, the output light signal being emitted according to a predefined field of view, the predefined field of view operating as a constraint to prevent devices outside of the field of view from detecting the output light signal;
configure the light detector to detect a second output light signal emitted by a second light emitter of the second system; and
in response to (i) detection of the output light signal by a second light detector of the second system and (ii) detection of the second output light signal by the light detector, enable secure communication between the system and the second system that uses the sensitive data accessed via the secure element.
