<p>A mobile wireless device is used to communicate with one or more wireless devices that correspond to predetermined physical locations. A product/service provider uses a mobile wireless device to broadcast a first digital message to one or more wireless devices that are within range of the mobile wireless device and that correspond to physical locations. A wireless device at a physical location responds to the first digital message by sending a second digital message to the mobile wireless device to provide requested information. The product/service provider then acts in accordance with the information in the second digital message. In this way, a product/service provider receives information that allows the driver to determine an appropriate course of action.</p> |
