How to Hack a Coke Machine





This is something that almost no one ever notices, every coke machine with a LED screen is hackable. You can find out cool stuff like how much money is in the machine, how many times one soda has been bought, etc.

Steps

Find a Coke machine that has an LED screen and says something like "Ice Cold Cokes".
Push the following buttons in the order given 4, 2, 3, 1.
If the buttons are in a column the first button is the top one.
If they are in a grid or other format, the first button is usually the top left one.
Now you have accessed the computer on the coke machine. Now you get to play around.
The first button is the back button
The second button is the up button
The third button is the down button
The forth button means enter. Or in some cases the Number Sign (#) will act as enter.

Example Commands

Cash
This command tells you exactly how much money is in the machine. This can also tell how many times a specific soda has been purchased.

Error
This shows the error messages of the machine. Basically it tells how many times a machine has been opened.

Exit
You will leave the menu.

Tips
Different machines have different commands, so learn what each new one does.
Some machines are more advanced than others. For example, I once found a machine that allowed me to change the internal tempature. Play around with it for a while.
If you need to get out fast (for example, the janitor is coming) press the change (coin return) button. This will normally quit the menu.
