Welcome to TRAY Self-Service Point of Sale

TRAY’s founder, Peter Kellis, was frustrated with always having to wait in line to order and pay at busy venues, so he put his undergraduate and graduate degrees in Electrical Engineering and Computer Science from MIT to work to create a solution that provided on-premise mobile ordering. Since then, TRAY has evolved into a full Point of Sale platform that is dedicated to providing service on-demand. Our goal at TRAY is to improve service around the world and make it a more enjoyable experience by allowing guests to order and pay how they want, when they want.
