What is the fee called when you use an ATM not owned by your bank?

The fee charged when you use an ATM not owned by your bank is commonly referred to as an "out-of-network ATM fee." This fee can be imposed by both the ATM operator and your own bank, resulting in two separate charges for a single transaction. It's important to check with your bank regarding their specific policies and fees associated with using out-of-network ATMs.
