Click to Pay: What It Is, and How to Use It Safely

Typing your full card number into a checkout page every time you shop online comes with a bit of risk. That information travels across the internet and lands in a merchant’s system you cannot really verify. Click to Pay, backed by Visa, Mastercard, Amex and Discover, was designed to make that safer.

What Is Click to Pay?

Instead of entering your 16-digit card number every time, you check out using your registered email and mobile number. Link your card once and after that, paying online becomes a quick, secure step rather than typing out your full card details again and again.

Why It's Structurally Safer

The biggest reason Click to Pay is safer comes down to how it confirms it is really you. Every time you make a payment, a One-Time Passcode is sent to both your registered mobile number and your registered email address. Not just one or the other.

This matters. A password can be guessed or leaked. A code sent to a single device can be intercepted. But requiring a code from two separate channels at once means a fraudster would need access to both your phone and your email to get through, not just one. 

On top of that, your actual card number is never sent to the merchant at all. Click to Pay uses tokenisation, meaning a secure digital stand-in is used instead. So even if that information were somehow intercepted, it would be pointless to anyone trying to misuse it.

What to Watch Out For

Because Click to Pay relies on your phone and your email to verify you, those two channels are exactly what scammers try to target. The most common trick is an OTP relay scam, which is when someone poses as your bank or a merchant, triggers a real login using your details and then asks you to read the code back to them. Once you do, they can use it to access your cards.

Scammers may also try to compromise your email or SIM card directly, or set up fake shopping websites that capture your OTP the moment you enter it.

How to Protect Yourself

Never share an OTP with anyone. Not your bank, not Visa, not a merchant. Nobody legitimate will ever ask you to read a code back to them. 

Keep your email and phone secure. Use a strong, unique password with two-factor authentication on your email and set a SIM PIN with your telco to prevent SIM-swap fraud.

Be careful on shared devices. Avoid staying signed in and clear your session when you are done. 

Check the website before entering anything. Scam sites can look almost identical to the real thing.

Turn on transaction alerts in the KAF DB app. You will know instantly if a charge you did not make goes through and can lock your Debit Card-i right away. 

If You'd Rather Not Use It

Click to Pay is optional. If you decide it is not for you, you can remove your card yourself at any time, either by deleting it during checkout or through Visa's card management portal, or call our Customer Support team at 03-8744 3331 and they will opt you out on your behalf directly through our system.

The Bottom Line

Click to Pay is safer than typing your card number into every checkout page, mainly because it checks two things you personally control, your phone and your email, before letting a payment go through. That protection only works as well as you protect those two channels, so guard them the same way you would guard your card.

If you ever spot a Click to Pay transaction you do not recognise, lock your card in the KAF DB app immediately and contact Customer Support at 03-8744 3331 to raise a dispute.
