Checkin takes too long

[GoogleCodeExporter]

At TXLF, where SCALEreg was in use, there were two people doing 'check-in',
resulting in really long lines there and then quick pickup after the
printers had done their job and printed out the badges.

I think check-in could be faster: Produce unique URLs or registration codes
that you give to the attendees as QR-codes or barcodes so that the human
checkers just have to scan them (which is quick!) instead of asking for
names to be spelled or etc.  If the URLs are also encrypted cookies,
they'll also serve as identity verification (since they'd be mailed to the
user upon pre-registration and payment).
