I thought activation is simply assigning PIN?
PIN can be set from IVR (by phone).

1) your supp card is combined-statement with Pricipal or separate-statement?

2) do you have PBe? does your supp cardholder has PBe?

3) in either your PBe or supp cardholder's PBe, can you see the supp card listed?

4) if not, follow this method here or here.

5) if still fail, last resort is to visit branch and bring the supp cardholder (parents) for fingerprint verification there

in my experience with supp separate-statement, the card is tied to supp cardholder's nric which in turn tied to PBe. ur parents don't have PBe, u gotta open new PBe and link the card to the new PBe. that is what I did.

however. someone shared before their supp card (separate statement) is linked to his principal PBe. I have no such luck doing this even at PBB branch.
if u don't need PBe, try IVR and activate the card. not sure what the ivr would request for validation. try and see how it goes.

card collection, no idea. all my supp cards delivered via postage.

IVR will send a TAC to registered mobile number for validation.

I activated my supp card through IVR and the following are required:

1. Supp card IC no.
2. Supp card no. last 8 digits
3. OTP sent to supp cardholder's registered phone no.

As for PBe, I remember supp cardholder with separate statement can only register for that at the nearest branch.

Try and call PB with a fixed line or other phone numbers (other than supp card's registered no.) for the IVR, so that you can receive the OTP instantly.

I experienced delays in receiving OTP to my supp's registered number while calling PB to activate pin during IVR with the same number. Waited too long for OTP to arrive until it failed.
