QR codes are becoming more and more popular, you see them just about everywhere. QA Codes is short for Quick Response Codes. QR Code symbol is a 2D barcode that can be scanned by handy terminals such as a mobile phone with CCD. The capacity of QR Code is up to 7000 digits or 4000 characters, and has high robustness.
The most popular QR Code app on iOS is QR Scanner.
History of QR codes
QR codes was created in 1994. A Toyota subsidiary named Denso Wave developed the code in order to help speed up the manufacturing process. The original QR codes help with tracking vehicles and parts. Since QR codes are able more information than bar codes, it created fast decoding speeds, hence the name Quick Response code.
How QR codes work
People scan the code using the camera on their smartphone and the app takes some action based on the QR code data:
- go to a particular website,
- show a product at the app store
- Email Template
- VCard Contact Information
QR Codes only reads data and doesn't transmit any activity or device data. For example, a QR code won't cause an instant sale, it will only bring you to a sales page where customers can enter in data.
There is a bit of controversy over who owns the worldwide rights to the QR code as a Germany company had apparently come up with the concept a few years before Denson Wave.
Some street billboards have included some large QR codes which make people wonder how drivers would be able to scan the code. Consumer Safety groups have argued that such billboards are distractions and could be a driving hazard.
The nation's largest billboard company, Clear Channel, has publicly promised to only use QR codes on billboards targeting pedestrian traffic.

Great post. I didn't know much about them. I suppose I'll have to download the app to use them one of these days. https://mhsusannematthews.wordpress.com/
