Techniques for checking into a retail establishment are provided. A retailer provides a substrate having a magnetic-field encoded tag. A consumer waves the consumer's device over the tag to electronically capture the magnetic-field encoded tag. The consumer's device is used to communicate the tag to a retailer to validate that the consumer is physically present and now checked into the retail establishment of the retailer.

A radio frequency noise reduction device and methods of operation are presented. The radio frequency noise reduction device identifies radio frequency noise on an isolated power plane of an electronic apparatus and generates an electrical signal that is injected into the isolated power plane and cancels the identified radio frequency noise. The generated electrical signal matches the frequency spectrum and amplitude of the identified radio frequency noise but the phase of the generated electrical signal is shifted by 180 degrees from the identified radio frequency noise.

Device and method for active reduction of radio frequency noise

One aspect of the present invention provides a multi-channel controller that can control a plurality of fuel pump devices, with each fuel pump device having its own dedicated communications channel. Accordingly, aspects of the present invention enable existing wiring and fuel pump devices to be preserved while turning an existing fuel pump device installation into a network of may point-to-point networks.
