Do you have a camera and is it setup?

[mampersat]

Yes - I have a camera plugged in. It worked for the first badge. My wife (works @ 150dow) has a badge, and I scanned hers and caused the above error.

[flynnguy]

I added this bit: https://github.com/mampersat/ElectricSlide/blob/master/pi/electricslide.py#L44

Which might help? I only have one card though.

I also just committed: https://github.com/mampersat/ElectricSlide/blob/master/pi/main.py

Which adds the start of the lcars interface. I didn't get much of a chance to clean it up but it seems to work so far. Doesn't take a picture or anything yet but I was able to get a handler to fire.

Closing since I have multiple users working now.
