Top ten myths about QR codes
Those fiddling black-and-white squares are taking over! Every newspaper drips with them, they tin can be seen in art galleries and shaved into footballer'south heads. Plainly someone thinks they're a good idea - nonetheless lots of people seem to go very irate at their very mention.
Hither's my quick guide to the top ten myths about QR codes.
1. QR codes can only incorporate a spider web address
It's true that the most pop use of QR codes is for URLs, but in fact they can contain whatsoever type of text. This means that you tin can use them to send emails, text messages, point out geographic locations, log in to WiFi, or even brand a phone telephone call.
2. No one is scanning QR codes
It'southward a popular meme that QR codes are fabricated by over enthusiastic marketing departments despite no one scanning them. Public statistics tin can be hard to discover, just TfL's QR codes in London are scanned by around 10,000 people per month. The QRpedia enabled exhibits in the Miro museum were scanned over 12,000 times.
3. Visual recognition will make QR codes obsolete
Wouldn't it be great to indicate your telephone at a poster and have it slurp the information off? Well, yes, but it's highly expensive and really impractical. It requires lots of centralised infrastructure and loftier computing power. At that place's also the tricky issue of homographic disambiguation - computers find information technology really tricky to tell the difference between 1!Il| or even 0 and O.
4. NFC kicks the arse of QR codes
Ahhh, NFC. The "cold fusion" of the mobile world. Like cold fusion it will revolutionise the manufacture and it's but a few years abroad! Sadly NFC has been a few years abroad for the last decade! In that location are virtually no NFC handsets on the market and the tags are expensive. Near every cameraphone can have a complimentary QR scanner and the codes are cheap to generate and print.
5. Information technology's piece of cake to damage a QR lawmaking
You know how you can scratch CDs and they will still play? They comprise error-correction which means that minor defects can easily be ignored. QR codes incorporate the same technology - significant up to thirty% of a code can exist damaged or obscured and the code volition notwithstanding be scannable.
6. QR codes await tedious
At that place's no demand for QR codes to look dull. Y'all can combine a variety of colours and logos into a QR code - just so long as y'all recollect non to obscure the three corner squares.
Take a look at these examples:
7. QR codes can be inverted
No. No they can't. Don't even endeavor this. Some QR scanners will endeavor to invert the image, but the majority just won't be able to cope.

8. You need mobile / WiFi signal to use QR codes
With the advent of WiFi in the London Surreptitious, this complaint has started to dry up. However, nearly every single QR scanner will store the results of a browse so you can access it once you're dorsum in coverage.
9. Information technology's really complicated to generate QR codes
There are a tonne of free and easy to use QR generators:
- ZXing
- QR Stuff
- QR Generator PHP (on GitHub)
ten. QR codes are easy to use
Perhaps the near contentious ane. Because it'south and then easy to generate QR codes there is a tendency for people to put them to really bad use. QR codes on billboards too high for anyone to scan, codes on motorways when cars are travelling too fast to scan, codes which atomic number 82 to non-mobile websites, codes hidden behind other objects - the list is almost countless.
Conclusion
QR codes are on an unstoppable ascension - they are being used by businesses both large and modest, they're used past activists and individuals, they're on billboards and badges.
They're free to use, and customers seem to have taken a shine to them. QR scanners at present regularly feature among the top downloaded apps from app stores.
Then, I say that information technology'due south fourth dimension to cover QR codes in all their blocky celebrity. Bound aboard the QR revolution and start scanning!
