Abstract
A system includes a beacon device including a communication strip having a plurality of directed light emitters distributed along the communication strip. The beacon device can transmit a directed light signal via the directed light emitters. The system further includes a tag including a processor, a radio frequency transmitter coupled to the processor, a directed light receiver coupled to the processor, and a lens having first and second major surfaces and a side surface, the tag to receive the directed light signal via the side surface and to transmit a radio frequency tag message via the radio frequency transmitter. The system also includes a radio frequency reader to receive the radio frequency tag message.
