Good use case: on a For Sale sign in front of a house or apartment with a deep link to the listing. Much easier than going to the web site and searching.


Sure, QR codes are always a "good use case" when it comes to this. They ARE faster than typing in a link or searching. Doesn't do much good when no one uses the code, though.


Usually they just link to a companies website though and it would have been faster to type it in instead of scanning it.
