I was looking at the dangerous things website and saw the use of a microchip for opening a garage door I have some metal boxes that I wanted to implement some sort of lock with do we open be in microchip. Any pointers from anyone familiar with this stuff, anything helps
You could snag something like this and integrate it in to the container/box/safe. I’m unsure of the compatibility with the xEM, I would think it should work just fine. If it doesn’t you can always just return it and try another, there are lots of different kinds of these drawer style locks available, this one just looked the most robust after a 30 second search.
