Definition
A debit card is a plastic card issued by a bank or building society that enables its customers to pay for goods or services at retail outlets by using the telephone network to debit their accounts directly. The retail outlets require a computerized input device, into which the card is inserted, and the customer usually taps in a personal identification number (PIN). Most debit cards also function as cash cards and cheque cards. In the USA, these cards are sometimes referred to as asset cards.
Historical Context
The origin of the debit card traces back to the 1960s with the advent of the first ATM cards, which allowed customers to withdraw cash directly from their bank accounts. Over time, the functionality of these cards expanded, integrating with the electronic point of sale (POS) systems to facilitate direct payments.
Key milestones include:
- 1966: The first debit card was issued by the Bank of Delaware.
- 1970s-1980s: Expansion of ATM networks and initial adoption of electronic debit card systems.
- 1990s: Wide acceptance of debit cards as a common payment method, further propelled by the introduction of EMV (Europay, MasterCard, and Visa) chip technology.
Types/Categories
Standard Debit Cards
Linked directly to a checking or savings account, these cards allow the cardholder to make payments and withdraw cash using the funds available in their account.
Prepaid Debit Cards
Not linked to a bank account, these cards need to be preloaded with funds before they can be used for purchases or withdrawals.
Electronic Benefit Transfer (EBT) Cards
Used by government benefit programs to distribute funds, these cards can only be used to make purchases as authorized by the benefit program.

Mathematical Models/Formulas
Compound Interest Formula for Account Balance
1A = P(1 + r/n)^(nt)
Where:
- \( A \) = the future value of the investment/loan, including interest
- \( P \) = the principal investment amount (initial balance)
- \( r \) = annual interest rate (decimal)
- \( n \) = number of times that interest is compounded per unit t
- \( t \) = the time the money is invested or borrowed for, in years
