Covid times has everyone doing this one thing (besides washing hands)…Scanning for SafeEntry using a unique QR Code!
But what is a QR Code?
? QR Code stands for Quick Response Code & it is a popular type of 2-dimensional barcode. True to its name, it is a code that is quickly readable by your mobile device, taking you to the specific website in a short time.
How does it work?
? A QR code is like a barcode that you see in a supermarket, except it has a much higher capacity of transferring information.
? Every QR code consists of a matrix of black squares and dots which encodes certain pieces of information. This information can be decoded by a handheld scanner or a QR Code scanning application on your smartphone.
? When your Smartphone scans this code, the app recognizes the intricate patterns & translates that information into something that can be easily understood by humans.
Who invented the QR Code?
?? The QR Code was invented by Masahiro Hara from Japan in 1994.
? Originally it was made to facilitate the easy tracking of vehicles and their parts while speeding through the production line.
?? Toyota Subsidiary, Denso Wave then announced the release of its QR Code, developed by a team led by Masa-sun. As people realised it’s use, it became more popular than anyone thought it would be.
Safe on track!
? Nowadays, many countries use QR Codes for SafeEntry to help log visits by individuals in public places, facilitating Contact Tracing. Once scanned, it takes you to the ‘check in’ page so you don’t need to enter and find the web site link every time.
Some quick and cool facts:
? QR Codes don’t have to only be black and white. As long as the device can tell the difference between the dark & light patterns, it should work.
? In Seattle, the QR codes are inscribed on some of the graves, giving the link to the information about the deceased person, the tag line being, “Every life has a story.”
