You can. But the process depends on your ability to access the Fi app!

If you currently have access to the Fi app: 

Please activate your card and set your ATM Card PIN before changing your device or updating your phone number/ email ID. 

If you are logged out or can't access the Fi app: 

• Place a call to our banking partner's self-help line. You can reach Federal Bank's IVR at 0484-2866700.
• After card activation is complete, you can log in to the Fi app.
• Be sure to enter the new details that require linking to your account. 
• After you've provided these details, we'll verify your identity. 
• For security reasons, the verification process includes a short video recording & your ATM Card PIN. 

Once the procedure is complete, we'll update your details. 

Now, you can log in to the Fi app once again.
