Can't read the code back out of the arduino though can you?
if you read out the arduino memory it's possible. Not sure how difficult it would be... But I don't think this is a problem.
Edit:
It is possible to get the assembly code back. so you could quite easy read the password out.
http://forum.arduino.cc/index.php/topic,3566.0.htmlBut still it would need access to the device....

Good call, didn't know you could do that. You don't get assembly though, you get machine code. It'd be a fair effort to trawl through it for a random password.
Doable, but a fair effort. I think at that point you're going to be compromised no matter what they have to do.
-
is possible to store the password on the ring and have the reader read the text from the ring and pass it on?
-
sure it would be possible but then everyone that is able to read your ring would have your password

That's why my reader sits behind my monitor so I have to reach around and I don't trigger it by accident.
I have a weird issue with my leonardo. If I have it connected continuously to my computer (Win8.1) it will disconnect and reconnect after a while (hardware removed and hardware installed sounds).
Anybody an idea what the problem could be? Or is this "normal" behavior?
-
I wonder if windows is scanning for new hardware and knocking it out?
-
I thought it could be because the internal timer is at it's limit and then re initializing the hardware but it does not happen every time
-
It could be that the usb hub is being over-loaded too.
-
yeah it seems to be an problem with that USB port.
