A recent trend in the fast food restaurant industry is remote order-taking at the drive-through. Such fast food chains as Hardee's Wendy's, Jack in the Box, and McDonald's have each experimented with remote order-taking at some of their drive-through windows. In the case of McDonald's, an experimental order-taking center takes drive-through orders for several different McDonald's locations. In addition, some McDonald's locations use off-site order-takers such as stay-at-home moms. Order-taker under both arrangements use voice over Internet protocol, or VoIP technology, a T1 phone line, and instant photographs to process the orders. A car pulling up to the menu board trips a magnetic loop that alerts the order-taker, who takes and confirms the order, enters the details on a computer screen, and transmits it instantly to the restaurant. In-store employees focus on taking the cash and delivering the food. Using photos of diners allows stores to install multiple drive-through lanes, which can boost car counts.
