Debit cards are an essential tool in modern banking, facilitating electronic transfers of cash from a customer’s bank account directly to a merchant’s account. These transactions are executed in real-time, effectively eliminating the need for checks or cash.
How Debit Cards Work
Electronic Transactions
When a customer uses a debit card to make a purchase, the transaction follows these steps:
- Initiation: The customer swipes, inserts, or taps the debit card on a point-of-sale (POS) terminal.
- Authorization: The terminal contacts the customer’s bank to verify available funds.
- Transfer: Once authorized, the funds are transferred from the customer’s account to the merchant’s account.
- Confirmation: The customer and merchant receive confirmation of the transaction.
The process typically completes within seconds, enhancing efficiency and convenience.
Banking at Home
Banking at home allows account holders to manage their funds through computer terminals or mobile devices. Functions include:
- Account Monitoring: Checking balances and transaction history.
- Funds Transfer: Moving money between accounts.
- Bill Payment: Paying bills electronically.
This form of online banking is another manifestation of debit account usage, simplifying daily financial tasks.

These are linked directly to a bank account and can be used for ATM withdrawals, purchases, and online transactions.
Prepaid Debit Cards

These function similarly to standard debit cards but also offer overdraft protection linked to a line of credit.
