A debit card is a payment card used to make purchases instead of using cash.

It is also known as a check card, cheque card, or bank card. A debit card typically displays the bank's name, the cardholder's name, a card number, and an expiration date. Unlike a credit card, which involves borrowing money, a debit card requires the funds to be in the user's bank account at the time of purchase. The money is immediately transferred from the cardholder's account to the merchant's account.

There are three primary ways that debit card transactions are processed. The first is the online debit system, also known as EFTPOS or PIN debit. This system requires electronic authorization for every single transaction. The debits are reflected in the user's account immediately. This method often uses a Personal Identification Number (PIN) for security. Because it provides live status and secure authentication, it is generally considered superior to other methods. The second way is offline debit, or signature debit. These cards connect to a bank account, but there is a delay before the money is withdrawn. The third method is the Electronic Purse Card System. This uses a smart-card chip to store value directly on the card.

Electronic purse systems allow payments even without network connectivity. These have been used in Europe since the mid-1990s. Notable examples include the Geldkarte in Germany and the Chipknip in the Netherlands. In Austria and Germany, almost all current bank cards include these electronic purse functions. However, the Netherlands has recently phased this system out. Most physical cards can include the functions of all three processing types. This allows one card to work in many different circumstances.

Debit card development has historically been country-specific. This created many different systems that were often incompatible with one another. For example, the United Kingdom used Switch and Solo systems. Canada used Interac, while France used Carte Bleue. China uses UnionPay, and India uses RuPay. To improve cross-border compatibility, many networks were re-branded. Many of these, such as Austria's Bankomatkasse, now use the Maestro logo. Maestro is part of the Mastercard brand. Since the mid-2000s, new initiatives have allowed cards from one country to work in others. This has also enabled use for internet and telephone purchases.

There are five major global debit card networks today. These are UnionPay, American Express, Discover, Mastercard, and Visa. Other networks include STAR, JCB, and Pulse. These networks provide the infrastructure for transactions to occur. Merchants may offer cashback facilities at the point of sale. This allows customers to withdraw cash along with their purchase. Most debit cards also function as ATM cards for instant cash withdrawals. However, banks usually set daily limits on how much cash can be withdrawn.

Prepaid debit cards are a specific type of card that can be reloaded. They are often used by unbanked people who do not use traditional banks. These cards offer several advantages, such as being safer than carrying cash. They also allow anyone over 18 to apply without creditworthiness checks. Users can deposit paychecks or government benefits onto them for free.

In the United States, the federal government uses these cards to make benefit payments. Some cities, like Oakland and Chicago, also use them for municipal IDs or transit passes. However, some prepaid cards have been criticized for having high fees on every purchase.

Using debit cards involves certain risks and consumer protections. If a user loses an unregistered card, they may lose the money on it. Additionally, if a card provider has technical issues, funds might be inaccessible. Fraudulent charges can cause problems because money is withdrawn immediately. This can lead to an overdraft or bounced checks. To prevent fraud, some countries have specific rules. In Singapore, Visa or Mastercard debit cards are disabled by default for international use. Users must manually enable international usage to prevent unauthorized activities.
