We have those security cards that unlock an electromagnet to get in the door at our workplace. Someone lost theirs in the parking lot and it got damaged. If you ever wondered like I have, here is what they look like on the inside.

Heehee home sick from work.
thanks! i DID actually always wonder what it looks like inside. i guess the wire loop needed in order to make a small electric charge inside the electronic circuit when moved inside the electromagnetic field created by the reader on the wall. in return i think the card emits a small transformed signal the other way around to be picked up by the reader.
an implant would be easier than the card
