Abstract: Using a combination of a device identifier and a reader identifier, a loyalty system is able to determine one or more loyalty applications a user is subscribed to. Additionally, by using a formulary based reward system, multiple tiers of rewards can be issued based on different categories of product or service purchased.

Abstract: A loyalty system is retrofit into an existing retail or purchase transaction system such that the system is inserted between a reading device and the reading device's associated original controlling hardware. The loyalty system is then capable of receiving information read by the reader and, for example, passively reading the data as if it is being transferred from the reader to the reader's controller or, actively reading the data and then determining if all, a portion, or derivative of that data should be transferred to the existing retail system. For example, this basic technology can be used to allow the loyalty system to accept, for example, information from an RFID tag and submit magstripe data to a magstripe controller as if the magstripe reader had originally read the magstripe data.

Abstract: Through the use of a tag that stores information including transaction information, loyalty reward information and trigger information, a loyalty system can avoid the necessity of contacting a central server to determine loyalty rewards. Furthermore, the tag can act as an electronic storehouse maintaining transaction information to facilitate, for example, record keeping, returns, saving paper, protecting privacy, and the like.

Abstract: Through determining one or more of the presence and attributes related to a customer, specific content is retrieved and presented to a customer. This content can be directed toward securing the customer as a member of a loyalty system. Alternatively, for example, the content can be dynamically chosen and delivered to a customer based on, for example, one or more preferences in a customer profile.

Abstract: The present invention relates to a low dropout voltage regulator comprising a noise reduction architecture. The low dropout voltage regulator according to the invention comprises a comparison stage for comparing a reference voltage signal with a feedback signal and for providing a first output voltage signal in dependence thereupon. The feedback signal is obtained from a node interposed between a first resistor and a second resistor of a voltage divider. The voltage divider is interposed between an input port for receiving an input voltage signal and ground and is connected to an output terminal of the comparison stage. The first output voltage signal is then low pass filtered prior provision to a gain stage. The gain stage provides gain to the first output voltage signal prior provision to an output port. The noise reduction architecture of the low dropout voltage regulator according to the invention is highly advantageous by providing high efficiency while high frequency noise is substantially reduced.
