<p>A wireless system, including a system controller (120), and a portable device (100) with wireless connection to the wireless system (101-106), can be used to link customers to the operations of a business. This link can be used to increase customer efficiency in the use of the business, including scheduling appointments to avoid lines, viewing customer locations on an interactive map, and tracking the locations of other customers traveling in a group. This link also allows the customer to initiate searches for information or products and to make electronic purchases. The business can use the link to send information or advertisements directly to select customers.</p> |
