QR barcode generators are cool. So cool in fact that one day they’re going to be a mad craze, you watch. Just as soon as someone works out how to use them on products for fun and profit via smartphone cameras and stuff. So, being one step ahead of the game, here’s our offering of a trio of QR generators you can use to encode virtually anything to be smartphone readable.

• Kaywa QR Code Generator. Very cool online barcode generator which copes with anything from URLs to phone numbers (stick that on your T-shirt and see who snaps it!). Available in a variety of sizes.
• QR Stuff Encoder. Similar online encoder, but this one offers colour, and can encode things like Google maps, a Paypal Buy Now linke (super useful!) and also has a section for embedding your codes onto things like caps, stickers, cups and apparel via Zazzle. Nice.
• Android QR Generator. Nice little Android app for your phone which will convert your choice of text into a QR barcode which you can show people via your screen. A cool way to deliver your website or email address perhaps?
