What? QR Codes are 3d barcodes that quickly get information into your device. They are convenient for long strings of characters that are difficult to type on a mobile keyboard aka wifi passwords and VPN (remote access) Pre Shared Keys (a long shared password).<\/p>\n\n\n\n
Why? If it is easy to change wifi passwords it might get done occasionally. PSK’s are long and some numbers and letters look the same. A QR code is not human readable, most users will happily give out the CORPORATE wifi password to any guest with a virus laden laptop. So print & post the GUEST wifi QRcode in your meeting rooms.<\/p>\n\n\n\n
Apple has supported pulling QR codes natively (no software to install) since iOS 10? and Android since v9.<\/p>\n\n\n\n
I created a QR code with all my info in vCard format and set this to the logon screen of my mobile phone. Now I can easily share my contact info with others or if I lose my phone and someone honorable finds it, they have all my contact info where they can see it, without needing to login.<\/p>\n\n\n\n
