A QR code is basically a barcode in a square shape. (Without
bars, ironically). It is scanned by a smartphone. It could direct someone to a
website, an image, a text message or, even, a phone number. (That’s totally up
to the QR code’s creator). For marketers, a QR code allows you to get
smartphone users to call you without forcing them to actually type in a phone
number or URL.
QR codes reduce friction.
How Popular Are They, Really?
