What's a QRCode?
This entry isn't about a specific gadget, but rather something some gadgets can actually read: QR codes. Quick Response codes are similar to barcodes. They are designed to make it easy to input data into a mobile phone. The included picture is a QR code.

QR codes have been used in manufacturing for the past couple of years. They are insanely popular in Japan where just about every phone sold has as a camera and the ability to read QR Codes. Higher-end Nokia devices have been shipping with a built-in barcode reader application, which will read these QR codes.

Denso Wave Incorporated, the creators of QR Codes, state that you can encode 4,296 of text into a QR code, or 1,817 Kanji/Kana characters. That's quite a bit of data. Other features, including built-in error correction, make this a great way to encode data in a machine-readable format that can easily be read later.

If you look at the QuickMark website, you can easily generate QR codes for a number of different types of data! QuickMark also provides software downloads for a number of mobile handsets which will turn your camera phone into a QR code reader!

If QRcodes were everywhere, would you use them? Leave your thoughts in the comments.
