Common everyday stuff here. If you don't recognize it, take a look
here.
We see it on every billboard, train and bus schedule, menu, printed adverts, flyers, etc. It's nice not to have to dig out a pen and write down things I want to remember... Just point my phone at the QRcode and press the button! All the fast-food places, donut shops, etc., use them for their discount coupons. Just show the cashier your phone!
If you have a Smart Phone, go to your free Apps location
and download a "QR Reader (scanner)." You will fall in love with it quickly! The train and bus schedules change often here, and rather than writing down an entire list of dozens of changes, I just push a button and have the schedule inside my phone. Discount coupons, URL's, maps and phone numbers to places, etc., etc., etc. It's really convenient!
