POS newbies can run it in a familiar "electronic cash register" mode, or in a customized selection of POS functions. Echo is a cloud play, providing redundant back-up of transactional data. Local storage keeps the business running despite Internet downtime. Optional POS modules also handle the restaurant management functions of employee management, timekeeping and table tracking.
