Mobile iCheck-in


CatCard iCheck-in Mobile App


With CatCard's iCheck-in Mobile app, checking in event attendees is a blast and easier at your campus events and club activities.

The ability to read attendee barcodes from either their MobileID smartphone or CatCard ID or manually in a pinch allows to cut down on event lines and helps with line busting. All data is kept in iCatCard's iCheck-in online portal, where event organizers and users can access and edit event details as well as view statistics and reports regarding attendees across multiple events. You can track attendance from anywhere, anytime, always online, and as many users at your events.

The Mobile iCheck-in app does NOT require a card reader or workstation/laptop, and it utilizes the camera of your device as a reader. This app works across iOS and Android smart devices.  Usage of this app requires a valid account from the University of California, Merced.
