Abstract: The embodiments set forth a technique for enabling a computing device to securely communicate with a peripheral computing device. According to some embodiments, the method can include the steps of (1) receiving, at a detection sensor of the computing device, a light signal from the peripheral computing device, wherein the light signal is received at a first frequency that is higher than a second frequency capable of being detected by a camera system of the computing device, (2) extracting information from the light signal, and (3) performing an operation using the information.
