As part of its ‘Helpfulness’ campaign (their tagline is ‘We're here to help you save’) American bank FirstBank is offering free books, free sudoku and free crosswords to travelers transiting Denver airport.
Passersby just have to point their smartphone to the QR codes and voilà. Here’s the link to the free books in case you’re interested or you can just try with the pictures above using a QR code reader.
Not as edgy as Hidden Sounds but very useful if you’re stuck in an airport.
