The main difference in the debit card vs credit card question is whose money you spend. A debit card takes money straight from your bank account. A credit card lends you the money, free if you pay the bill in full by the due date and at about 27.8% to 27.9% a year if you do not. On fraud, both are covered by the same S$100 liability cap in the Association of Banks in Singapore’s Code of Practice.
This guide compares protections, costs, rewards, overspending risk and overseas use, from the ABS code, MAS, MoneySense and the banks’ own terms, as at November 2026.
The short version: For fraud, the protection is similar. For cost, a credit card paid in full each month is free and earns rewards; carried over, it is expensive. A debit card cannot run up debt beyond what is in your account, which suits anyone who finds it hard to pay in full.
Debit Card vs Credit Card at a Glance
| Debit card | Credit card | |
|---|---|---|
| Whose money | Yours, from your bank account | The bank’s, repaid by the due date |
| Interest | None on purchases | About 27.8% to 27.9% a year if not paid in full |
| Fraud liability before you report (ABS code) | Capped at S$100 for debit cards that work like credit cards | Capped at S$100 |
| During a fraud investigation | The money has already left your account | No interest or late fees on the disputed charges |
| Rewards | Varies by bank; check the card’s page | Cashback, miles or points on many cards |
| Overspending | Limited to your balance (unless overdraft is allowed) | Limited to your credit limit; balances can grow with interest |
| Builds credit history | No | Yes, if paid on time |
| Income test | None from MAS | S$30,000 for citizens and PRs aged 55 and below |
| Overseas cash withdrawal | From your own account, with bank fees | Cash advance: fee plus interest from day one |
Protection Against Unauthorised Transactions
The ABS Code of Practice for Banks on credit cards sets the rules. Before you tell the bank your card is lost or misused, your maximum liability for unauthorised charges is S$100, unless you acted fraudulently, were grossly negligent or did not tell the bank as soon as reasonably practicable. Banks may waive even the S$100. The code says this S$100 limit “also applies to all debit cards which function like credit cards”, for purchases locally, overseas and online.
The code also says you are not liable, if you did not act fraudulently or with gross negligence, when your card was not stolen but its details were used for phone or internet purchases, or for unauthorised PIN transactions. The banks’ own terms say the same: DBS’s debit card agreement caps your liability at S$100 if you report promptly, and says you are not liable for transactions after the card is reported and blocked.
Where MAS’s E-Payments User Protection Guidelines fit. These guidelines cover bank accounts and other payment accounts, including how losses from unauthorised transactions are shared. But MAS states that their liability split does not apply to credit, charge and debit card transactions on cards issued in Singapore, because those cardholders already have the ABS code’s protection. Some duties in the guidelines still apply to card issuers, such as telling customers about their protection duties. The guidelines ask account holders to report unauthorised activity as soon as practicable.
The practical difference. The ABS code says interest and late fees are not charged on credit card charges while they are investigated. With a debit card, the disputed money has already left your account, so you are without it until the case is resolved.
Disputes and Chargebacks
If goods do not arrive or a charge is wrong, you can ask your bank to dispute it. Citibank’s FAQ on chargebacks, which covers credit, debit and prepaid cards on the international card schemes, says most banks ask for a dispute form within 14 days of the statement date, and that resolution takes about four weeks for simple cases and up to 12 weeks for complex ones. Contact your bank as soon as you notice the problem.
Rewards, Interest and Overspending
Credit cards earn cashback, miles or points, which a debit card may not match; see our best credit cards in Singapore page and the full card table. Those rewards only count if you pay in full. MoneySense reminds readers that a credit card “is a form of borrowing” and should not be used as long-term credit.
Worked example (illustration only). You spend $1,500 a month. On a 1.5% cashback credit card paid in full, you earn about $270 a year. In one month you leave $1,000 unpaid for 30 days: at 27.8% a year that is at least $20 of interest, and more if your bank also charges interest on the paid part from the purchase dates. That wipes out roughly a month’s $22.50 of cashback. Miss the minimum as well and the $100 late fee wipes out about four months’ worth.
A debit card cannot run up a debt you did not have, though DBS’s debit card agreement says the bank may let the account go overdrawn at its discretion and charge an overdraft fee.
Overseas Use
Card spending in foreign currency. DBS charges foreign transaction fees of up to 3.25% on both its credit and debit cards. Other banks charge similar fees; our guide to overseas card fees and dynamic currency conversion explains them.
Cash withdrawals. On a credit card, an ATM withdrawal is a cash advance. DBS, UOB and Citibank charge 8% of the amount or S$15, whichever is higher, plus interest from the day of withdrawal. With a debit card you withdraw your own money, but overseas ATM fees still apply; check your bank’s fee page. Our credit card interest guide has a cash advance worked example.
Building a Credit History
MoneySense explains that your credit report records your credit repayment history across banks. A debit card is not credit, so it does not add to that record. A credit card paid on time does, which helps when you later apply for a loan. Our guide to the credit score in Singapore covers how the score is built.
What To Do Next
- If you pay in full every month without strain, a credit card can earn rewards at no cost. Set up full payment by GIRO.
- If you sometimes carry a balance, consider using a debit card for daily spending until it is cleared, and plan the payoff with the debt payoff calculator.
- Turn on transaction alerts on every card, and report anything you do not recognise to the bank straight away.
- Before travelling, check your cards’ foreign transaction and ATM fees on the bank’s own page.
