What happens when you insert your card and enter your PIN

When you put your card into an ATM, the machine reads the magnetic stripe or chip on the back and asks for your personal identification number (PIN). This four- to six-digit code is what proves the card belongs to you. The ATM connects to your bank's system in real time to check that your PIN is correct and that your account has enough money for the withdrawal you're about to request.

Once your PIN is verified, the ATM shows you a menu of options. The most common choice is withdrawal — taking cash out of your account. The machine will ask you how much you want and then dispense bills from its internal cash drawer. The entire transaction takes 30 seconds to two minutes, and your bank records it immediately.

If you enter your PIN wrong three times in a row, most ATMs will keep your card for security reasons. You'll need to contact your bank to get it back, usually by calling the number on the back of your card or visiting a branch in person.

Key Takeaways

  • Your PIN is the only thing that protects your account, so never share it with anyone, including bank employees or ATM technicians.
  • Most ATMs let you withdraw cash, check your balance, transfer money between accounts, and deposit checks or cash, depending on the machine and your bank.
  • ATM fees vary by bank and machine — your own bank's ATM is usually free, but using another bank's machine may cost $1 to $3 per transaction.
  • The ATM screen will always show you the amount being withdrawn before you confirm, so check it matches what you asked for.
  • If the machine doesn't return your card or your money, contact your bank immediately — most have a 24-hour dispute line.

Finding an ATM that won't charge you a fee

Your bank owns a network of ATMs, and using one of those machines is almost always free. The easiest way to find one is to open your bank's mobile app or website and search for "ATM locator" — it will show you every machine your bank operates near your current location, along with their addresses and hours.

If you use an ATM owned by a different bank, you will usually pay a fee. The fee comes out of your account immediately, and the amount varies — some banks charge $1.50, others charge $3 or more. Some banks reimburse out-of-network fees if you have a premium checking account, so check your account agreement or call your bank to ask.

Convenience stores, grocery stores, and gas stations often have ATMs run by independent networks like Allpoint or MoneyPass. These machines may charge a fee, but they're sometimes cheaper than using a different bank's ATM. The fee will appear on the screen before you confirm the withdrawal, so you can cancel if you don't want to pay it.

Withdrawing cash and checking your balance

After you enter your PIN, the ATM menu will show you several options. Select Withdrawal to take money out. The machine will ask you to choose an amount — usually in preset increments like $20, $40, $60, or $100, though most ATMs also have a "Custom Amount" option where you can type in exactly what you need.

Before the cash is dispensed, the screen will display the amount one more time and ask you to confirm. This is your chance to catch a mistake — if you asked for $100 but the screen says $1,000, press Cancel and start over. Once you confirm, the machine will count out your bills and push them into the slot at the bottom.

To check your balance without withdrawing money, select Balance Inquiry from the main menu. The ATM will show you your current account balance and sometimes your available balance — the amount you can actually withdraw right now. This balance updates in real time, so it reflects any deposits or charges that happened earlier that day.

Depositing checks and cash at an ATM

Many ATMs accept both checks and cash deposits, though not all machines have this feature. Look for a slot labeled "Deposit" or check your bank's app to see which machines near you accept deposits. The process is slower than a withdrawal — the machine scans each check or counts each bill, so allow five to ten minutes.

For a check deposit, select Deposit from the menu and choose Check. The ATM will ask you to insert the check into the slot, usually face-up and facing a specific direction — the screen will show you which way. The machine scans the check to read the amount and routing number, then asks you to confirm the deposit amount. Once you do, the check is pulled into the machine and stored.

For a cash deposit, select Deposit and choose Cash. You'll insert your bills into a slot one at a time or as a stack, depending on the machine. The ATM counts them and displays the total on the screen. Confirm the amount, and the cash is pulled into the machine. Both types of deposits usually post to your account within one business day, though some banks take longer.

Transferring money between your own accounts

If you have more than one account at the same bank — such as a checking account and a savings account — you can move money between them at an ATM. Select Transfer from the main menu. The machine will show you a list of your accounts and ask which one you want to transfer money from and which one you want to transfer it to.

Enter the amount you want to move, and the ATM will display it for confirmation. Once you confirm, the transfer happens immediately — the money leaves one account and appears in the other right away. This is useful if you need to move money from savings to checking to cover a bill, or if you want to move money into savings to keep it separate.

Some banks limit how many transfers you can make from a savings account per month — often six transfers total, including ATM transfers. If you hit that limit, the ATM will reject the transfer and tell you to contact your bank. This is a federal rule, not something your bank chose, though some banks have removed this limit in recent years.

What to do if the ATM keeps your card or doesn't give you your money

If an ATM doesn't return your card after the transaction, it has been retained for security reasons — usually because you entered your PIN wrong multiple times or because the machine detected suspicious activity. Your card is safe inside the machine. Contact your bank's customer service line (the number is on the back of your card) and tell them which ATM location kept it. They can retrieve it for you, or they can cancel it and mail you a new one.

If the ATM takes your money but doesn't dispense it, or if it dispenses the wrong amount, contact your bank immediately. Have the receipt from the machine if you have it — it will show the exact time and amount. Your bank can pull the video from that ATM and see what happened. If the machine malfunctioned, your bank will credit your account for the missing money, usually within one to three business days.

Some ATMs are not connected to the internet and process transactions offline — these are rare but still exist. If you use one and it doesn't connect, the transaction may not go through at all, or it may go through hours later. If you're unsure whether a transaction completed, check your account balance on your phone or at another ATM before you leave the location.

Protecting your PIN and staying safe at the ATM

Your PIN is the only thing standing between someone else and your money. Never write it down, never tell it to anyone, and never enter it where someone can see the keypad. This includes bank employees — your bank will never ask for your PIN over the phone or in person. If someone claims to be from your bank and asks for your PIN, hang up or walk away.

When you're at an ATM, stand close to the keypad so people behind you can't see your fingers. Cover the keypad with your other hand while you type. If the ATM looks damaged, has loose parts, or has anything attached to the card slot, don't use it — it may be a skimming device designed to steal card information. Report it to your bank or the business that owns the machine.

Use ATMs in well-lit, busy locations during daylight hours when possible. Avoid ATMs in isolated areas or late at night. If you feel unsafe, leave and find a different machine. Your safety is more important than the convenience of that particular ATM.

Frequently Asked Questions

Can I withdraw more cash than my account balance?

No. The ATM will only let you withdraw up to your available balance. If you try to request more, the machine will reject the transaction and tell you that you don't have enough funds. Your available balance may be less than your account balance if you have pending charges that haven't cleared yet.

Why does my ATM receipt show a different balance than my phone app?

The receipt shows your balance at the exact moment you used the ATM. Your phone app may show a slightly different balance if transactions have posted since you left the machine. Both are correct — they're just from different times. Your bank's official balance is what appears in your account right now.

What happens if I forget my PIN?

You can't use the ATM without it. Contact your bank's customer service line and ask them to reset your PIN. They'll verify your identity by asking security questions or other information, then they'll either give you a temporary PIN over the phone or mail you a new one. The process usually takes one to three business days.

Do ATMs have daily withdrawal limits?

Most banks set a daily limit on how much cash you can withdraw from an ATM — commonly $300 to $500, though it varies by bank and account type. If you need more cash than your limit allows, you can visit a bank branch during business hours and withdraw money from a teller. You can also contact your bank to ask if they'll temporarily raise your limit.

Is it safe to use an ATM at night?

ATMs themselves are safe to use at any time — the machine doesn't care what time it is. Your safety depends on your surroundings. Use ATMs in well-lit areas with other people nearby, and be aware of who is around you. If you feel unsafe, wait until daylight or find a different machine in a busier location.
