QR Codes seemingly are becoming more commonplace in the world today. I, myself, am probably one of 3 people worldwide without a smartphone thus unable to use a QR reader. The convenient possibilities in QR codes seem endless as I’ve seen them on so many types of products I use daily. I’ve noticed they are made up of many unique patterns but my question is will it come to a point where there are no more QR codes because all of the patterns have been used up (see IPv4)?
Answer
Obviously as the QR code is made of a matrix of fixed size dots, either black or white, there will be a total limit of variations.
However don’t think of QR codes as IP addresses, think of them more like encoded URL’s – certain combinations of dots may be no use to anyone. Current QR codes can store up to 1852 chars.
However if you look at the wikipedia article http://en.wikipedia.org/wiki/QR_code – there have been various versions of QR codes, it wouldn’t surprise me if at some point a newer standard superceeds current QR codes with either a bigger matrix of dots, smaller dots or both.
