QR (Quick Response) codes are gaining popularity due to their mass adoption by larger global brands and the fact they can carry quite a lot of information. You may have seen these little squares used on labels of your favourite soda, or perhaps on a billboard or magazine advert. QR codes can carry a myriad of information, in fact you’d be amazed at how much can be stored within a QR code and you’d also be surprised to find out that due to nifty error correction up to 30% of the QR code can be damaged with the resultant data still usable!
How much data?
So what is the maximum information you can get into a QR code? The table below shows how packaged a QR code can become, and as long as the reader application understands the type it can do just about anything with this information including preparing an SMS to send to a campaign which could be to fetch a voucher, enter a competition or even request a callback.
- Numeric only – 7089 Characters
- AlphaNumeric – 4296 Characters
