Eventor is an attendance tracking app that enables attendees to check in and out of an event by scanning their QR codes through event volunteers. The timestamps of check-in and out help the event manager mark the attendee present. Only the event manager is authorized to give attendance and sole purpose of QR code scanner is to check in and out member.

Problem​
