I have made a design for an expansion card that would allow the laptop to read RFID Cards.
I thought this would be very useful for those stupid company laptops that require 2-factor authentication every time you need to open the system. So, the user can just tap an RFID Authentication Card on the laptop, and voila! Logged into the system without any hassle.
This is not an original idea at all if you have been wondering
I have basically ripped off the schematic from a Sparkfun USB RFID Reader.
Check out the PCB design here:
I am a beginner at making PCBs so excuse any amateur errors
