Functional Requirements (What the ATM does)

* The ATM must allow authenticated users to withdraw cash from their linked accounts, up to their available balance and daily limit.
* The ATM must provide users with the ability to view the current balance of their accounts.
* The ATM must verify the user’s identity by validating their entered Personal Identification Number (PIN) against the bank’s central database before allowing any transactions.

Non-Functional Requirements (How the ATM behaves)

* The ATM should be operational and available to customers 24 hours a day, 7 days a week, with a system uptime of at least 99.5%.
* Each transaction (e.g., withdrawal, balance check) should complete within 10 seconds under normal operating conditions.
* All communications between the ATM and the bank’s servers must be encrypted using industry-standard encryption to protect user data and prevent fraud.
