DFW introduced a program that links the Foursquare and Facebook Places location-based mobile applications to 85 (so far) of the airport’s concessions. Now if you check in when you’re at the airport you’ll see deals and discounts offered at food outlets and shops right around you.
For the next several weeks, you’ll notice “brand ambassadors” in the terminals telling people about the service, teaching them how to use it and handing out giveaways.
Back in April, Hartsfield-Jackson Atlanta International Airport introduced discount offers available via quick response (QR) codes printed signs around the airport.
The QR codes direct passengers to the airport’s mobile website — www.iflyatl.com — where there are downloadable discount coupons.
The TSA is also using QR codes. According to a recent post on the TSA Blog, the agency is testing QR codes on checkpoint signage at a few airports to point travelers to information about lost and found, customer service, procedural information and travel tips.
