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 as I read those demons "crosswords"?!

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

This is an example:

As you can see, the big, big advantage is that one can directly scannear the code with the phone and if the content is a URL, it automatically opens the browser with 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 the automatic generation of code (depending directly on the URL of each page), so if you want to see the current page in the phone, I just scannear achieved with this code at the bottom 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 as appliances are going to have to use registration, reemplezando the bar code.

Generators:

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

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

* Podes directly use the URL to generate your own tecnoloco 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 one you can download the version for your phone

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