SHOPPING CART POSITION SENSING SYSTEM |
摘要 |
A shopping cart display system and position sensing system includes a cart mounted display that is responsive to trigger signals provided by transmitters associated with a particular location. When the display receives a unique trigger signal, it displays advertising media associated with that location. In one embodiment, the display includes a sensor for determining whether the information is displayed in the presence of a consumer, and a memory for storing all trigger signals received during a given shopping trip. The stored data is transmitted to a polling transceiver located at a point of sale register for later analysis and gives a log of all locations that the cart has visited.
