Love ’em or hate ’em, QR (quick response) codes do have their uses.
Yes you can try to be clever and incorporate design into the little QR ‘bligger’. Ideally you might point people to video and exciting content that might dazzle and excite; ooohhh, ahhh!
But, they can simply be a good way for people (smartphone-users) to catch your contact details / web content.
I’ve previously mentioned the Safe Space material that I’ve designed and I’ve just produced some A3 posters that have a QR element.
The personal nature of the Safe Space service is something that people might think of interest ‘in passing’, ‘click’, and it’s in their phone for future use.
Nothing clever but – it’s there and might be useful to someone “in passing”.
