Activating your FAB Debit Card is a mandatory step before you can withdraw cash or make purchases. The most secure and instant method is via the FAB Mobile App, which allows you to set your 4-digit PIN immediately without visiting an ATM.
Do this next
- Log in: Open your FAB Mobile App.
- Locate: Have your physical debit card ready (you will need the CVV).
- Security: Ensure you are not on public Wi-Fi when setting your PIN.
Method 1: Activation via FAB Mobile App (Recommended)
This method is instant and activates both the card and the PIN for online/offline use.
Step 1: Navigate to Services
Log in to the FAB Mobile App. On the home screen, tap the “Menu” (bottom or top corner depending on OS) or look for the “Cards” dashboard.
Step 2: Select the Card
Swipe to find the inactive debit card (it will often be greyed out or marked “New”). Tap on “Activate Card”.
Step 3: Verify Details
Enter the CVV (3-digit number on the back of the card) and the Expiry Date printed on the front.
Step 4: Set PIN
The app will prompt you to enter a 4-digit PIN. Confirm the PIN. You will receive an OTP on your registered mobile number to finalize the activation.
Method 2: Activation via FAB ATM
If you prefer not to use the app, or if you are already at a mall, you can use any FAB ATM.
Step 1: Insert Card
Insert your new FAB debit card into the ATM slot.
Step 2: Verification
The screen will recognize the new card and ask for an Activation Code (sent to your registered mobile via SMS) or prompt you to generate an OTP.
Step 3: Set PIN
Follow the on-screen prompts to enter your desired 4-digit PIN. Once confirmed, the machine will eject your card, and it is ready for immediate use.
Activation Limits & Security
| Feature | Details |
| Time to Active | Instant (App & ATM) |
| Cost | Free |
| First Transaction | Must be Chip & PIN (Contactless might not work until used once with PIN). |
| SMS Code | 2121 (For alerts, though App is preferred for activation). |
Pro Tip: Your first purchase after activation must be a “Chip and PIN” transaction (inserting the card into the machine). Contactless “Tap to Pay” features often remain disabled until the physical PIN is used once at a merchant or ATM.
Final Thoughts
Using the FAB Mobile App is the superior method as it avoids the risk of shoulder-surfing at an ATM while entering your new PIN. Remember, FAB will never call you to ask for this PIN or the OTP generated during activation.
Frequently Asked Questions
Can I activate my FAB debit card via SMS?
While credit cards have a direct SMS command, debit cards are best activated via the App or ATM to securely set the PIN simultaneously.
How long do I have to activate my card?
You should activate your card immediately upon receipt. If left inactive for over 3–6 months, the bank may block it for security reasons, requiring a new card issuance.
Does activating the card activate online shopping?
Yes, but you may need to enable “Online Usage” explicitly within the FAB App under “Card Controls” to allow e-commerce transactions.
