Abstract: Methods, systems, and devices are disclosed for proximity sensing and guidance of a user to a desired item's or items' location within a place. In one aspect, a system includes a tag device attachable to an item located at a location in a place and including a processing unit, a transceiver to wirelessly transmit a beacon including a code associated with the item and to receive a communication signal from a user device attempting to connect to the tag device based on the code, and an output to generate an output signal to draw attention to the device; and a data processing device to process information about the item from the user device to determine the item and associated code, such that when a user desired item is determined to be the item attached to the tag device, the tag device is operable to produce the output signal.
