Physical to the digital world! The Code Semacode (and others like it: Barcode , Data Matrix , MaxiCode , QR Code ) is conceptually equal to the typical bar code products from the supermarket, basically contains data (oddly enough! ).

The difference from the typical bar code is that it only stores numbers, whereas the Semacode (and derivatives) stores characters, which can be stored phrases, personal data, or better yet: URLs!

And how the hell I read these "puzzles"?!

To read need any reader compatible. (Effective response if any!), The latest camera phone models support reading of these codes!, Such as the N95.

This is an example:

As you can see, the big, big advantage is that one can directly scan the code with the phone and if the content is a URL, the browser automatically opens to that URL!, With the obvious savings to write the full URL into the cell (of course, the phone must have internet)

Possible uses:

* For example the blog I put this automatic generation of code (depending directly from the URL of each page), so if you want to see the actual page on the phone, I only achieved with the code scanner is at the end of the right column. (Look for a widget for WordPress and I found they were not: S)
* Surely, the magazine / paper diary will soon have the code, both the content and advertising, pointing to some URL.
* T-shirts with a code "hidden"
* The supermarket products such as appliances are going to have to use registration, reemplezando the bar code.

Generators:

* Sisi, right here, through the power of ELTECNOLOCO! .... ok, google, to find this solution in php (Thank you!) and implement!

<span > eltecnoloco.com</span>	(Use "Save Image As" to download the generated image)

* You can use these directly tecnoloco URL to generate your own Semacode, as follows: http://eltecnoloco.com/sc/?type=png&size=150&text=http://eltecnoloco.com , replacing the type (type), size (size) and text (text) (used as the SRC of the IMG tag)

* Plugin for Firefox: Mobile Barcoder , undoubtedly you have to have it, do not write anymore a URL on the phone!
* Google has an API to generate, but I did well at the time, maybe today I walk better, as I saw this updated API.
* Reader J2ME (Java-enabled phones): From this page or this other version you can download for your mobile

Note: Not if you saw, Movistar public about street signs with QR code similar to, but it is called BIDI, and owns (salami), this will generate and send an MMS obviously charging you!
