How ATMs work

Explore why your PIN is proof of identity.

In this lesson

How ATMs work is part of Cards and ATMs. This preview shows how banking-basics connects to everyday family decisions such as earning, saving, spending choices, goals, approvals, or parent-guided money conversations inside Progress Penguin.

Think about this money choice

Imagine this situation: You insert your card at a GTBank ATM, enter your PIN, and select 5000 in local currency.

How it works

Your PIN is proof of identity. Without it, the card is useless. This is why sharing your PIN — even with family — is dangerous. The PIN is your authentication, not just a formality.

Try a real-life example

Real-life money moment: You check your balance at an ATM (30000 in local currency), then withdraw 10000 in local currency, then use your debit card to buy 4500 in local currency of groceries.
