Abstract: The presentment and redemption system offers discounts directly to consumers through their mobile phones. The discounts are based upon the user of the mobile phone meeting a targeting criterion and the discounts are determined using the targeting criterion. Mobile phone users that do not meet the targeting criterion are not eligible for the discount. Because the discounts can be targeted to each individual consumer, there can be a better correlation between consumers' interests and the transmitted discounts.

Abstract: In some embodiments, techniques for rewarding presence include detecting a presence of a mobile phone within an enclosed space, transmitting information relating to the presence of the mobile phone within the enclosed space to a server computer, wherein the server computer processes an award for the presence of the mobile phone within the enclosed space, wherein the award is associated with a user account associated with the mobile phone; and receiving from the server computer information relating to the award.

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.

Abstract: The present invention relates to an electronic device and methods of distributing content to at least one user, comprising the steps of: transmitting mass media content to a user device for being reproduced to the user; matching content which is related to the mass media content, information descriptive of the mass media content, and data which is related to the user; transmitting the resulting matched related content to the user device for being reproduced in combination with the mass media content to the user; and receiving and processing user feedback data transmitted from the user device, the user feedback data being representative of a reaction of the user with respect to the reproduced resulting matched related content and mass media content.
