Embedded RFID For Online Passwords

[Jair2K4] is using his unique RFID tag address as an online password. We’d bet that if you went far enough to get an implant in your hand you’d continually search for a reason to use it. Wanting to do more than just start his car with a wave of the hand, he built an interface module out of an Arduino and a Parallax RFID reader. Using a program called AAC Keys on Windows 7 he emulates a keyboard using the input from the Arduino. When it comes time to login he types his username and parks the cursor in the password box. By holding the RFID implant next the reader, the ID is dumped as the password, along with a newline (might be a carriage return, we’re not certain) character which submits the login. Take a look for yourself after the break.

On the one hand, nobody will be able to steal his tag as easily as they could steal one that is on a key ring. But we know RFID is rather notorious for a false sense of security. As long as you’re not using it for state secrets we think it’s a nice solution.

Update: After reading the comments on this feature, [Jair2K4] made some changes to his code. It now reads the tag and verifies it with stored data, then spits out whatever password you wish (making it easy to change passwords from time-to-time). He also added servo control to the sketch.
