is it possible to update the profile again after the pengesahan and perakuan? just realize some wrong data after submitting the profile

If they continue with this approach, should be no issue of someone else using you IC number to register, since he can not get any payouts, unless he opens a bank account using your name as well.

Seriously don't know who approved or designed the registration proses.. I'm not in IT, and I'm IT noob also can detect the flaw in registration right away.

Maybe the best way is.. enforce the OTP must come from same owner or same household. If not, submit request with phone bill attached, and PADU staff will review.. yes, review millions of them. But not everyone use family plan. It's gonna be hassle, but at least registration is protected.

Or figure out an easier method before releasing PADU
