Hi all,

I have the Mifare 130 RFID Module with the sparkfun shield and I found some infos and sketch by Tom Igoe.
It works to read my tags but now I would like to (e.g) display an image if the reader reads a defined ID.
I tried to make a function (at the end of the code) who would show the image as soon as the reader reads the tag but it gives me a "unexpected token" error.

I think i closed all the brackets and i registered the function in the draw method but i honestly don't know if the code would work like this. Any idea?
Thank you!
