what is difference between atm card and debit card

The main difference is in their functionality and acceptance.

• An ATM card is limited to cash withdrawals at Automated Teller Machines (ATMs) and checking your bank account balance.
• A debit card provides all ATM functions, plus the ability to make purchases at merchant stores and for online payments.
• Debit cards are widely accepted for digital transactions as they generally feature a network logo like Visa or Mastercard, which ATM-only cards typically do not have.
