The Redstone ATM is a very clever machine which can be used for conveniently managing your valuable items in Minecraft while making sure they are kept safe. It’s entirely powered by redstone and command blocks and it can host a multitude of different accounts and keep track of a wide range of items without problems.
How does it work?
Open the chest and take one of the key cards. There are both fake key cards and real ones. It’s to demonstrate that you will need a specific key card to access certain chests and if you try access the ATM with a fake on you won’t gain access.
Insert the obtained key card into the dropper and then press the button on the right side of the ATM to request access to your account. It’ll short thereafter analyze your request and depending on your key card determine a process.
In this case, I inserted a functioning key card and as a result I got access to the minecart with a chest. It’s basically the account which contains the account’s items or blocks.
You can either deposit or withdraw items from the chest. Don’t forget to get the key card from the chest before closing your account (also known as pressing the button to push the minecart back into the vault).
