Using a debit card to pay online is straightforward as long as you’ve got the plastic handy and are comfortable making virtual transactions — though paying with a credit card may be safer.

How to use a debit card online

When you’re ready to buy something online, follow these steps to use your debit card to complete the purchase:

1. Select your payment method

Go to your shopping cart and select “debit card” as your payment method. If that’s not an option, you can typically select “credit card” instead. You may also need to indicate the type of branded debit card you’ll be using, be it Mastercard or Visa Debit.

2. Enter your debit card details

You’ll typically need to enter:

• The 16-digit number on the front of your card
• The expiration date listed below the 16-digit number
• The CVV CVV stands for card verification value and is simply the security code on the back of your card. , which is a 3-digit number listed near your authorized signature.
• Your name as it appears on your debit card

3. Provide your billing information

Some merchants may ask for the billing address linked to your debit card as well. Make sure it matches your bank records. Otherwise, your transaction may be declined.

4. Authenticate the transaction

You may also be asked to complete a two-step verification. This is a security measure that requires you to confirm your identity by entering a code sent to your phone, email or banking app before the transaction is approved.

5. Confirm and finalize your payment

Check your order summary carefully before confirming. Once it’s processed, you’ll likely get a confirmation email or receipt.

Which debit cards work online?

In Canada, there are three debit cards that work online: Visa Debit cards, Debit Mastercard cards and Interac Debit. Most major banks issue Visa and Debit Mastercard cards, and you can use them to shop online, pay bills and make international purchases.

Some banks give you the option of having an Interac Debit card as well as or instead of a Visa or Mastercard Debit card. However, if you want to use your Interac Debit card online, you have to add it to your Apple or Google wallet. And, not all merchants offer Apple Pay or Google Pay as a payment method.

Is it safe to use a debit card online?

Using a debit card to pay online is generally safe with a secure internet connection. In 2024, online sales accounted for an estimated 6.1% of total retail sales in Canada. Consequently, the safety infrastructure in place is growing stronger.

Here’s what you can do to verify security:

• Check for the lock. There should be a lock icon in the upper-left corner of the search bar of your screen, next to the web address. This indicates that the site holds an SSL certificate and that the information you submit will be private.
• Monitor your account. Review your account for suspicious activity after making a debit card purchase online. If you have your mobile bank app downloaded on your phone, enable push notifications to see transactions in real time.
• Ensure a secure Internet connection. The best practice is to only make online payments on a secure and private connection, such as a home network. Public Wifi at airports or coffee shops isn’t as safe.

Remember that there are always risks associated with making debit card payments, and it’s likely easier for thieves to intercept your information online than in person. If hackers do get access to your debit card information, they could steal funds from your chequing account.

What if someone steals my debit card information online?

If you see fraudulent activity on your account via your debit card, report it immediately. Contact your bank as soon as you notice the activity. You can also report it to the Canadian Anti-Fraud Centre. If you’ve been the victim of debit card fraud, see our guide on how to get a refund on a fraudulent transaction.

Paying via credit card vs. debit card online

In general, using a credit card for everyday purchases is less risky because credit cards aren’t linked directly to your bank account. This means you can cancel a transaction before the money is withdrawn from your personal account.

Credit card companies tend to be more lenient with fraudulent transactions, with some providers offering zero liability for their cardholders, meaning that you aren’t responsible for fraudulent activity if someone steals your card information. Some credit card providers also offer extended warranties on purchases.

If using a debit card is your only option to make a payment online, make sure you’re comfortable with the risks associated.

Bottom line

Using a debit card is convenient and generally safe, although not risk-free. If you’d rather use a credit card, find a provider that offers perks and rewards that work best for you.
