I work at Waterstones and we now wear one on a lanyard so if we see people in store with a smart phone we can ask if they want to scan it and be taken to our mobile site!!
That's bad. I mean, it's fine for the customer, but not for you.
"Hello Sir/Madam, would you like to scan this QR code and go to our mobile site so you can shop there instead, meaning I will be out of a job this time next week when the store closes and everything goes online only?"
It's like people in supermarkets asking customers to use the self checkouts because they're faster (save for another argument about if it is faster or not). Management are asking these people to effectively do themselves out of a job. I'm sure that when they get rid of the staffed tills, they'll also axe the job where someone invites people to scan themselves!
Anyway, QR codes are useful although I do think that sometimes it's silly to get someone to scan a code on the tube, to get a URL that they can't access because there's no signal. If the app doesn't have a history, or offer to put it your bookmarks, you'll simply ignore it. And if you did save it in your bookmarks, would you remember to go to it again later?
NFC will do away with needing to scan anything, which is fine too, but I am sure they'll still only send text or links. What you need is an updated version that can send much more data to a device in the short space of time you're waving the phone over it - as in a matter of a second or less.
When this comes, you can then download a self-contained app (the phone even able to tell the chip to send specific code for that device/platform), images or even a video. I think that this is a little way off though, although I have seen some trials that are pretty impressive.
You walk into a book shop and someone comes up and asks you if you would like to try out their website? Sheesh im there because I DONT want to use a website.
I think it is totally unfair that staff are often made to do things that could affect their own job. The problem is, there's probably some manager overlooking staff that would be moaning if the public weren't made to have a barcode thrown into the face of a customer.
I bet people in WH Smith hate having to ask everyone buying a newspaper, magazine or a packet of crisps if they'd like to buy a bar of chocolate for £1 or whatever else they've got stacked up on the counter, or staff in a clothes shop asking if you'd like to not pay with the cash you've already got in your hand but sign up for a store card at 3000% APR to get 10% off.
