As we said in our post “Yes, Size Matters… but not that much” the main problem of mobile phones in order to read a small 2D code are its limited optical (macro/focus). They do very badly in short distance.3, 2, 1… Attachable lens to mobile phone cams. ¡Whoooaaa!

It’s true, it is an awful artefact that would only be used by someone stacking 6 pens and 2 pencils in his shirt pocket, and that carries around a compass, a calculator watch and broken glasses. In other words, a Nerd (just like you and me). Don’t foul yourself, if you are reading this blog -or even worse, if you have it on your RSS reader- at this moment you are likely to be part of a group like this on your High-School years.

We don’t think this is going to be the ultimate solution. However it is clearly pointing out a need that mobile phone users have that companies have to consider.
If you think that you will not get away without one of these gadgets here you have a link to a store that sells them (Japanese only) where you can get one for about 1000 yen and see some other models.
