Hello!
Now I’m not trying to steal credit card information or do anything illegal, I am an engineering student and I want to build an automatic cat feeder that opens when it senses the right microchip. I was doing some research about how to scan microchips from further away (about 5 inches) and I came across this post that said there was a hacker convention where they demonstrated how to do it. What perfect people to ask!
So if anyone has any info I would greatly appreciate it!
