The present invention includes systems and methods for facilitating transactions using non-traditional devices. Photolithography, various etching technologies and electroplating are used to form the micro probes on the surface of the ceramic substrate. The residential gateway includes a network switch, a network interface device in communication with the network switch wherein the network switch is configured to select at least one of the first or second voice channels for voice communication over the broadband communication line. The O-ring, in its natural free state condition, has an axial dimension which is less than the width of the groove by an amount such that when the article is received in the body and the O-ring makes sealing contact with the article, the O-ring is deformed into the space between the side walls of the groove. Additionally, the dynamic checklist may receive and present external data, and may provide for pilot interaction. As the rate at which notifications are received increases, the interval between scans also increases.
