Abundantly useful

14 January 2015

It’s nice when things just become quietly, abundantly useful.

QR codes have gone from something people plastered over business cards and adverts in failed attempts to appear cutting-edge, to the default pattern for moving information along the following interaction:

a web transaction → time passes → queuing up for something → human interaction → scan → some sort of change of state.

Quickly thinking back over the past year I’ve:

  • Printed a paper ticket and had it scanned using an abnormally large laptop in a rainy queue at The Fall gig at Electric Brixton.
  • Had a PDF scanned to get on the Amtrak Coast Starlight.
  • Had a printed ticket scanned using adapted phone scanner in the queue for some club in Portland and Bob Mould / Liars at Village Underground.
  • Waved a code embeded in an app against an entry gate to the Eurostar.
  • Printed out a label and stuck it to a package to Amazon via Collect+
  • Had a an email scanned on my phone queing to see a film at the Ritzy.
  • Had a ticket in Apple’s Passbook scanned on the way in to see a baseball game
  • Scanned my laptop screen using my phone to load a TOTP security token to a Yubikey
