What is Debit Card & How Does is Work?

Debit and credit cards have become essential for managing payments in today's cashless world. Whether buying groceries, shopping for luxury items or paying utility bills, these cards simplify transactions and offer convenience. With their widespread use, it's no wonder debit cards have become a popular choice for many.
Despite their prevalence, many people still find themselves confused about what debit cards are. Let's clarify their meaning and functionality.

A debit card lets you make payments directly from your bank account with just a single tap. It functions similarly to a credit card for transactions, but you use your own funds instead of borrowing money. Debit cards can be used at various locations nationwide for purchases and online bill payments, eliminating the need for cash.
Many people wonder if an ATM card differs from a debit card. They are essentially the same; debit cards also function as ATM cards, providing access to cash when needed.
Most debit cards are linked to major networks like Visa or Mastercard; you will see their logos on your card. To complete transactions, you must enter your PIN at stores, ATMs, or online.

You will find a 16-digit Debit Card number on the front of your debit card. This unique number is crucial for identifying your card and is divided into two significant parts:

• First Six Digits: The Issuer Identification Number (IIN) or Bank Identification Number (BIN) identifies the card issuer, such as Mastercard or Visa.
• Digits 7-16: These digits represent details specific to your bank account, including the bank’s name, the type of card, and other unique identifiers.

An ATM number, commonly referred to as a PIN (Personal Identification Number), is a secure 4-digit code associated with your debit card. This PIN is used to verify your identity during ATM transactions. You can set and customise this PIN when you receive your debit card, ensuring it's easy for you to remember. If you forget your PIN or need to reset it, banks provide a simple process for making changes.

Offline Transactions:

• When you use your debit card in person, the payment is processed through a card machine.
• The merchant inputs the amount, you enter your PIN, and the transaction is completed swiftly.
• Your bank handles the payment request and deducts the amount from your account, sending you a confirmation notification.
   

Online Transactions:

• For online purchases, enter your 16-digit debit card number, expiry date, and the 3-digit CVV code from the back of the card.
• After entering these details, an OTP (One-time Password) will be sent to your registered mobile number.
• Enter this OTP on the merchant’s site to finalise the transaction.
   

Understanding how your debit card works helps you use it safely and effectively, maximising its benefits in today’s digital payment landscape.
