I love this idea. You know how much of a hassle it can sometimes be to log on to a WiFi network in your friend’s house or office? Mostly because if they’re not techie oriented they never remember the password?

Well all they’ve got to do is use this WiFi Joiner Android program to create a QR code with all the details, and then when anyone visits they can just take a bar code scan and the settings are automagically installed onto the phone. Instant network connection.

The amount of times I’ve had to scrabble around under desks or in awkward places to try and recover some obscure password stuck to the back of a router/modem. This is a great way to avoid all that. It’s also perfect for places that offer public WiFi like cafes etc. Awesome!
