Waiting in lines to get in the door at a hackathon sucks.
What it does
Let's organizers crunch through lines of attendees to do more important things.
How I built it
Built the Android part using a QR scanner.
Built the web interface with Express on Nodejs.
Parse handles all the data.
Challenges I ran into
I wanted to use Parse's anonymous/automatic users, but that's kind of difficult if the organizer needs to sign in on a website and on a phone.
Accomplishments that I'm proud of
What I learned
I should do more research before starting a project.
However, my argument is that Checkin to Eventbrite as Mandrill is to Mailchimp.
What's next for Checkin
Polish the Android app (allow multiple organizers to sign in).
Make the front end actually nice.
