The native apps and desktop have the ability to record check-ins against events. If your conference is providing CME accreditation it is a good idea to add this check in menu so users can easily track which events they have checked into over the course of the conference.
We also have the ability to prevent checkin to a session unless you are within 15 minutes of the start/end time of that session
Reach out to your Zerista project manager to get this setup as a menu/action in your app!
