From the makers of Fashion GPS, an invitation, scheduling, and seating system used by the fashion industry since 2006, comes Events GPS. Launched in August, the service offers electronic invitations, mail merge, interactive seating plans, and on-site digital check-in that can be done with QR codes or with R.F.I.D. chips embedded in physical invitations. Events GPS has a Web-based system and a mobile app. Hosts can use the system to store contacts, including photos, and track which events people attended in the past, where they were seated, and other details. After the event, Events GPS can generate reports regarding attendee engagement.
