WTH is an RFID module?

post #1 of 3
Thread Starter 
Hey all! Been upgrading my M6600 slowly. Replacing parts here and there. The latest part I replaced was the palmrest. I bent the old one a bit replacing the CPU. Anyway, the new palmrest I bought has a fingerprint reader... but I noticed some strange plastic thing that wasn't on my old one. It's an "RFID" module. It's pretty big and fits under the palmrest to the right of the touchpad. What does it do? I've searched but I'm rather confused. Thanks!

here's a pic of the part

EDIT: Some have called it an RFID reader.

RFID stands for Radio Frequency Identification. It functions as a contactless smartcard reader.

Radio Frequency Identification. Basically in a nut shell a low end model can be picked up by a scanner almost like a barcode reader but if the item with the RFID tag is in range you don't actually have to scan the item. My company uses some that are sateliite based and we can ping and see our assets moving in real time. It's a great way to track vehicle's in Iraq and Afghanistan were such assets tend to grow legs.
