Abstract
An electronic device identifies that it will transmit a matrix code to a display. Then, the device may transmit a signal to a matrix code reader. The signal instructs the reader to perform a matrix code capture action such as playing an alert, powering an optical reader, launching a capture application, and so on. The device may evaluate one or more conditions before transmitting and the reader may evaluate one or more conditions before performing the action. The device may transmit the signal to any reader within a communication range, only to readers on a matrix code reader list, and so on. Additionally, a reader may transmit a confirmation message to the device when the reader captures a matrix code after receiving a related signal confirming that the matrix code was captured successfully.
