As of apple iOS 11 native QR-code scanning is available by launching the camera. Before iOS 11 we had to rely on 3rd party apps full of Adds and very suspicious behavior.
Apple has built QR Code recognition directly into its camera app, which means all you need to do is open it up and point it at the code in question.
There’s also a built-in QR reader in the Wallet app on iPhone and iPod. To access the scanner, open the app, click on the plus button at the top of the “Passes” section, then tap on Scan Code to Add a Pass.
QR codes have been around for many years. QR code (abbreviated from Quick Response Code) is the trademark for a type of matrix barcode (or two-dimensional barcode) first designed in 1994 for the automotive industry in Japan.
here are a few of the many applications of this versatile standard.
- QR code payment
- Website shortcut
- WiFi network login
WiFi network login is a perfect use, here we can display a QR code in place of post-it or a whiteboard and not “shout” the password to every passerby.
