Log in to your computer with a swipe of your hand! Use an NFC ring and reader to type in your password for you with an Arduino Leonardo, which can act like an HID keyboard.

Cool! I want this to be my first among a lot of things: first Arduino, first wearable, first NFC project, and first replacement for my wedding band.

@mscruz5445 8 лет назад

awesome.. thanks guys for sharing this

@user-gs3fq9pd5o 7 лет назад

hello. i have an arduino uno. i must do the same thing ( for the pin 6 ) to the shield? i want the project only for reading the passwd and not to typing the passwd on the pc . thank you

@h2bjon934 8 лет назад

can I use this to do multiple things? For example unlock my phone, computer and even a hose door?

@Thenerdyteacher 8 лет назад

Can I use any NFC tag with this code, or does it have to be the ring? I've added the code to the Leo and open the window and nothing happens. Just a blank window.

Perhaps better to use this as a second authentication factor (a la Duo Security/RSA tokens). That way, if your password is stolen...someone still can't get in without stealing your ring (or duplicating it).

Is the ring stainless steel? I have a nickel allergy and I can’t wear stainless steel.

Why not use a Flora or the feather or another atmega32u compatible like the Pro Micro? A Leonardo seems overkill for something like this!

@adafruit 8 лет назад

+jorenmartijn Leonardo uses the same 32u4 microcontroller as Flora and many of the Feathers. Its used for its HID keyboard support in this case, and the form fits easily with the shield!

@miko007 8 лет назад

from an it-sec point of view, this is an absolute disaster. you literally could pin your password to the screen instead.

@AerikForager 8 лет назад

Now to install a switch into the NFC ring so you can control WHEN it is readable...

@cyrus565 8 лет назад

but is there a wrist band instead of a ring?

@adafruit 8 лет назад

+Cyrus565 yes!

@fratoren2679 6 лет назад

i think that makes easy to hack the password if iam not wrong

@CooperDuper3000 8 лет назад

Nice ring, but storing your password on an NFC tag? Not a good idea...

@Ponsaillle 8 лет назад

+CooperDuper3000 If I undertand well you don't save the password on your nfc but on the arduino.

@TheKeyote 8 лет назад

+Ponsaille That's correct. You could not get the password from the NFC tag. You could however spoof the UID if you were able to scan their tag or you could decompile the arduino and extract the password from that. Overall not super secure but then again neither is a windows password.
