QR Codes : What are they?
QR Code is a type of 2 dimensional bar code which is used to store numeric and alphanumeric data in an encoded matrix pattern form. It was first designed and used in automotive industry in Japan (in 1994 by Denso Wave). Since then it has gained its popularity and is widely used due to its fast readability and comparatively greater storage capacity. QR Codes have since been frequently used in advertising strategy since it is more quick than manually having to type urls.
QR Codes may be occasionally useful but most often needless. You can find qr codes in stores, posters, magazines, ads and even in some websites. You only scan them if you really need to or find the ad/information interesting. The use and applications of qr codes is limited due to the resources it requires, which includes; an smartphone with camera, qr app to interpret the code and data connection to load the url or web content. QR codes were one of the coolest thing back in years when it was developed but even now lots of advertisers use these codes and there are also many websites that let’s you create one (mostly-for-free).
