The ImIn App is a solution to track individuals required attendance to their organization’s events utilizing the latest mobile technology. Features like geofencing (tracking attendance based on a mobile device's geographic location) make this app a great alternative to the regular ID card or QR code scanners. This app allows the user to check in/out of an event just by pressing a button on their mobile device. ImIn will require biometric authentication and the device's geolocation to verify attendance. Many organizations (e.g. universities) currently depend on several computers and laser scanners to track, for instance, required attendance for residential students. Crowded bottlenecks could be avoided, and resources efficiently utilized with an app like ImIn.
