Hacking gas pumps for free gas.
On the internet you can find articles from years back about how people have been able to somehow hack into gas pumps and get free gas. Anyone ever done this?
Ways that iv heard;
1. sometype of electronic card.
2. accessing a hidden menu to change the price. and other say to open the pump up itself
Many say to find a owners manual for the pumps.
Can anyone shed some light on this?
