Elevation ten myths about QR codes
Those little black-and-white squares are taking over! Every newspaper drips with them, they can be seen in art galleries and shaved into footballer'due south heads. Plainly someone thinks they're a good idea - yet lots of people seem to get very irate at their very mention.
Hither's my quick guide to the superlative 10 myths about QR codes.
1. QR codes can only contain a web address
It's truthful that the most popular use of QR codes is for URLs, but in fact they can incorporate whatever type of text. This means that you can utilise them to send emails, text messages, point out geographic locations, log in to WiFi, or even make a telephone call.
2. No one is scanning QR codes
It's a popular meme that QR codes are made by over enthusiastic marketing departments despite no i scanning them. Public statistics can exist hard to observe, but TfL's QR codes in London are scanned by around ten,000 people per month. The QRpedia enabled exhibits in the Miro museum were scanned over 12,000 times.
3. Visual recognition volition make QR codes obsolete
Wouldn't it be great to point your telephone at a poster and accept it slurp the data off? Well, yes, simply information technology'due south highly expensive and really impractical. It requires lots of centralised infrastructure and loftier computing power. There's also the catchy event of homographic disambiguation - computers detect it really tricky to tell the difference between one!Il| or fifty-fifty 0 and O.
iv. NFC kicks the arse of QR codes
Ahhh, NFC. The "common cold fusion" of the mobile globe. Similar cold fusion it will revolutionise the industry and it's just a few years away! Sadly NFC has been a few years away for the concluding decade! There are nigh no NFC handsets on the market and the tags are expensive. Almost every cameraphone can have a free QR scanner and the codes are cheap to generate and print.
five. It's like shooting fish in a barrel to damage a QR code
Y'all know how you can scratch CDs and they will still play? They contain error-correction which means that modest defects can easily exist ignored. QR codes contain the same engineering science - meaning upwardly to 30% of a lawmaking tin can be damaged or obscured and the lawmaking will still be scannable.
6. QR codes look boring
There'south no demand for QR codes to await slow. You can combine a diverseness of colours and logos into a QR code - just and so long as you call back not 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 try this. Some QR scanners will effort to invert the image, but the bulk just won't be able to cope.

8. You lot need mobile / WiFi signal to use QR codes
With the advent of WiFi in the London Cloak-and-dagger, this complaint has started to dry out up. However, near every single QR scanner will store the results of a scan so you can access information technology once y'all're dorsum in coverage.
9. Information technology's really complicated to generate QR codes
There are a tonne of free and like shooting fish in a barrel to apply QR generators:
- ZXing
- QR Stuff
- QR Generator PHP (on GitHub)
10. QR codes are easy to use
Mayhap the almost contentious one. Considering it's 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 loftier for anyone to scan, codes on motorways when cars are travelling too fast to scan, codes which pb to not-mobile websites, codes hidden behind other objects - the list is almost countless.
Conclusion
QR codes are on an unstoppable rise - they are beingness used by businesses both big and small, they're used past activists and individuals, they're on billboards and badges.
They're costless to use, and customers seem to accept taken a shine to them. QR scanners now regularly feature among the elevation downloaded apps from app stores.
So, I say that it's fourth dimension to embrace QR codes in all their blocky glory. Spring aboard the QR revolution and starting time scanning!
