I' not spanishhh. Portuguese from Portugal. I have a web2py app to control all outside workers via an RFID reader. I use arduino to read the card and send it via serial. Then in the local PC I have nodejs to read it and call a web2py service that via tornado sockets updates a web page. My web2py app is in the amazon cloud. It works so fasttttttttt just under 20 lines of nodejs.amazing!
