QR codes have infiltrated our daily lives quickly, shacking up in coffee shops, Web sites, and business cards all over the world. They are terrific for delivering info quickly and smart folks are uncovering all sorts of cool ways to make the most of them.
1) Share Wi-Fi access. I wrote this up a while back, but it’s pretty great: Wifi Joiner lets you create and post a QR code that embeds access info for your wireless network. This is great for home networks, coffee shops, and plenty of other places. For the moment, though, it’s Android-only.
2) QR codes aren’t just for boring business marketing. We recently checked out Barcode Gallery, a company that sells QR codes (two-dimensional bar codes that link to messages or Web sites) as wall art. Now you can emblazon those codes on a custom T-shirt for a high-tech fashion statement with ScanMe’s shirt-printing service.
3) Quickly get codes for shortened links. Both bit.ly and goo.gl link-shortening services offer a really neat feature: just append “.qr” to the end of any one of the URLs to get a QR code that links to the same site. This is by far the easiest way to get QR codes for Web sites, though for now it’s limited to these two services, as far as I can tell.
4) Create multicolor codes with logos embedded. This is pretty cool, and incredibly easy. The French site Unitag lets you turn URLs, text, and certain other data into colorful QR codes with embedded logos for free. As Nicole says, make sure you try it out before sharing it!
5) Get reminders as you leave the house. If you use an online task manager like Google Tasks or Remember The Milk, it’s easy to create a tag called “Leaving the House,” “Leaving Work,” etc., then create a QR code directing to that page. Post it at the door, or anywhere else you’ll be sure to see it when leaving, then scan it for reminders of things you need to do before leaving. At the very least, you won’t forget your phone anymore!
