In some embodiments, apparatuses and methods are provided herein useful to monitor point of sale terminals and provide information to customers, via a lighting system. In some embodiments, information is provided, via visible light, to consumers and, via invisible light, to the management of a retail shopping facility. For example, a notification system for monitoring point of sale terminals in a retail shopping facility may include one or more visible light emitting status lights, at least one non-visible light emitting status light at each of the point of sale terminals, one or more optical sensors configured to detect the non-visible wavelength and an intensity associated with the non-visible wavelength emitted from the at least one non-visible light emitting status light; and a control circuit.
