USB Stick NFC Ring Logging Into Desktop by Nairod 785
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.
It is possible to get the assembly code back. so you could quite easy read the password out.
But 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.
