Reading data from RFID Reader

Hello!

I am having quite a problem trying to read the RFID hex data from the arduino. I am using an arduino Duemilanove and a ID-20 Innovators RFID reader. Using the code from the arduino site Arduino Playground - ID12 and the serial monitor, i get the reading correctly. But how do I send the data to processing?

I want processing to see the card data, compare it with a database and show in screen a name linked to that card. I know how to program that but i need to send the card data from arduino to processing. and that's not working.

Any ideas?

Maybe instead of sending the hex data of the card in parts, store it all together in a String and then send it via serial.

thanks!

Exactly the same way. Processing simply replaces the serial monitor as the application reading the serial data.

What are you doing? How is Processing reading the data? How is it "not working"?

Simply says "it doesn't work" wastes everybody's time.

Any ideas?

Well, yeah, as a matter of fact, I do. POST YOUR CODE!
