First Claim
Patent Images
1. A method, comprising:
- generating an identifier that identifies a retail store; and
transmitting the identifier in the retail store using an ultrasonic signal transmitter that transmits using at least one ultrasonic frequency;
wherein a server-side processor determines presence of a user at the retail store based on information received from a client-side application of a mobile phone of the user in response to reception of the transmitted ultrasonic signal at the mobile phone of the user, wherein the server-side processor provides the user a reward for presence in the retail store via the client-side application of the mobile phone of the user while the user is present at the retail store, and wherein the server-side processor facilitates varying the identifier transmitted by the transmitter according to a schedule.

Abstract
The transmission system transmits an encrypted identifier ultrasonically in an open-air environment using an ultrasonic transmitter. The ultrasonic identifier is associated with a location, which may be a store or a department within a store, and may be received by a microphone on a mobile phone. The identifier may be used to infer presence of the mobile phone user at the location associated with the identifier. The transmitter may include an ultrasonic transducer. The system may further provide a reward, responsive to inferring presence at the location.

46. A method, comprising:
-
generating an identifier that identifies a retail store; and transmitting the identifier in the retail store using a signal transmitter that transmits using Bluetooth; wherein a server-side processor determines presence of a user at the retail store based on information received from a client-side application of a mobile phone of the user in response to reception of the transmitted Bluetooth signal at the mobile phone of the user, wherein the server-side processor provides the user a reward for presence in the retail store via the client-side application of the mobile phone of the user while the user is present at the retail store, and wherein the server-side processor facilitates varying the identifier transmitted by the transmitter according to a schedule. - View Dependent Claims (47, 48, 49, 50, 51, 52, 53, 54, 55, 56, 57, 58, 59, 60, 61)
