Unlock your Mac/PC with Arduino RFID Card

In this tutorial I'll show you how to unlock your Computer or Macintosh with an Arduino and a RFID tag.
Arduino sketch, library and schematics can be downloaded here:
Don't forget: the UID is your password. You have to change it in the system settings. Works on Mac, PC and Linux.

In the sketch you provided there is also a folder with .cpp and .h files....do we need to zip it and add it to the library on arduino or just the .ino file upload gets the work done??

[lonesuvivor]

is it possible to code a 2 factor authorization so that, it asks password after we tap rfid??

Hi ! Can this work on Raspberry Pi ? Or can I plug this Arduino/rfid to a Raspberry Pi ? how to proceed to change/add a PAM directory for this rfid ? you explained well except that we see the input of ID card, yes, but next frame we're already on user authentication display .. please ! I really need help on this project

I had a problem. After reading all the comment I tried to change the sketch and test it in version 1.0.6, but the error remains the same: this report is more information with
"Show verbose output during compilation"
enabled in file > preferences.

Hi, has anyone solved the following problem?
If my iMac is in sleep mode, the RFID unlock works fine. But if the Mac does a new start, the RFID unlock didn't work.
Has someone solved this?
Thanks.

I am sorry that you ran into problems, i will help you. Simplest method: Try upload the sketch using Arduino IDE 1.0.6 (just google it) If you want to upload it using the normal IDE, you have to change a few things:change rst pin to pin 9 and change in code to this: #define SS_PIN 10 #defineRST_PIN 9 and add: #include <Keyboard.h>

You have to read out the IiD of YOUR card. Not the code of mine card. Search Google: "Read UiD Arduino RFID". Thanks

hi Julkramer can you please let me know your email address so that i have to ask you few questions regarding this project!
Thanks

change rst pin to pin 9 and change in code to this:
#define SS_PIN 10
#define RST_PIN 9
and add:
#include <Keyboard.h>
