What can you do with an ATM?
For standard ATMs, especially those installed at banks, there are a range of functions you can reasonably expect them to be able to perform. This includes:
Withdrawing funds. Almost everyone who has ever interacted with an ATM has withdrawn money at least once. This was the original purpose the machine was conceived for and continues to be a very popular activity.
Checking balances. Most ATMs will give you a balance update with every transaction, but you can also just use it to check your account balances.
Accepting deposits. Although it's less commonly known, ATMs can accept deposits of cash or checks. Online banking has made depositing checks a lot more secure than dropping them into an ATM, but it's still a function that's available.
Transferring funds. If you need to move money between your accounts, this is also a function that your ATM can perform. Again, it's probably a little easier to do this on your phone, but this remains an option.
Making payments. For ATMs attached to banking institutions, you can often make payments on any lines of credit you may have with the bank. You won't likely be able to pay other institutions, but you can make payments to your bank from the accounts you hold there.
