The idea is that a mouse has an optical sensor embedded already. Why not perhaps, add a capability to read QR codes.
The idea is that if this capability was integrated with web browser support, it would make accessing QR code more convenient (just as we are already partially doing so with our mobile
phone (except that we still have too start the QR reader app to read a code)

Whatever next? A printer driver which automatically renders URIs as QR Codes? |

Because QR codes are blind links which are inherently dangerous and the sooner they go away the better, therefore let's not develop new technology around bad ideas. |

No different from any shortened URI you might
find in a twitter stream, and hardly any worse than
a fully formed URI on a domain with which you're
not familiar. You don't know what you'll find at
www.example.com (unless you've visited before). |
|
| |
You always must rely on the context in which the
link is shown for a clue as to what you might find if
you follow it. Applies to QR codes as well as
shortened URIs and full URIs. |
|
| |
This would only work if you scanned the mouse back
and forth repeatedly so as to cover the whole of the
QR code. |
|
| |
It might, however, work for straightforward
barcodes... |

People should not follow those either. Even trusted sources can be fooled. |
|

QR codes are more dangerous, actually. In the real world they can be pasted over, changing a trustworthy-looking code in an ad into something malicious. Also they are directed at mobile users who are probably less knowledgeable about malware threats, and are using devices which usually do not run any threat protection software. |
|
| |
Anyone who knows to check is safe. |
|
| |
Most people don't know to check. The typical mobile user has no idea about the dangers, nor what to watch for. QR codes are marketed directly at this group. |

CueCat did something like this, only it wasn't QR codes it was barcodes, and it wasn't a mouse it was a cat. <See link> |

^and it wasn't software related but was a type of fruit smoothie. |
