The present disclosure is directed to automatically determining customer information in response to detecting that a customer's mobile device is located at a retail location. A mobile device of the customer may detect a communication from a wireless communication beacon, and may send a customer ID to a backend server. Upon receiving the customer ID, the backend server may access customer information, and transmit it to a server of the retail location. The server may, in turn, cause a customer mobile device in the retail location to display the customer information, thus facilitating effective and efficient customer service. With the customer's permission, upon detecting the customer's mobile device, customer information may be pushed to a salesperson's device or information (e.g., insurance quote or claim information; new vehicle financing, feature, or review information; or other product or service information) may be pushed to the customer's mobile device.
