Adding a uart interface a cheap rfid usb reader 125khz

I got the idea from this video. Seemed pretty simple, and all the rights for this idea goes to the author of the video, I just posted the process. http://youtu.be/RcZI6fK948w

First

Open the case, 4 screws.

And this is the reader bare naked.

Second

Locate the UART pin headers.

 The four holes looks like a 5v, gnd, rx, tx pins!!

Third

Solder some wires.

Fourth

Test it out using a uart-ttl adapter.
