Trim SmartStart QR codes

I noticed however, that the QR cod text copied from the camera included a trailing space after the last digit. When I backspaced, the QR code was accepted.

I checked the other two outlets, and they all had the same trailing spaces.

The only thing I could say that the app could do is do a sanity check when it scans the QR code with the camera, look for trailing spaces, and delete them. I would think that would avoid this problem in the future.
