CheckIN is a useful tool for recording of presence. It could be used for attendance marking for event, meeting, class, work and etc. All it needs is just a scan of a QR code by users. Interestingly, you can use it under online and offline situation, and even restrict attendance to only specified group users.
Forget about paper and pen recording of presence, forget about typing on excel. You can now better use your time for more important daily agenda, and leave your mundane tasks to CheckIN.
