Why would a credit card application ask for my debit card PIN number?

I know, I shouldn’t expect anything remotely normal from an online form in Japan.

I’m signing up for an Amazon credit card, which ultimately spit out a pop up window, asking for the PIN number for the debit card for the bank I will use to pay the credit card.

Is a PIN number just normal information you hand over in Japan? I’ve already been asked to hand write it and mail it to the bank before which I refused.

Of course the PIN number was set while applying for the card online, but why would that be required to view information online? I’m not paying the credit card with the debit card, it’s a transfer. I already log in and view the information on the website with an email and password, not my debit card information.

  1. The pop-up windows should be the system of your own bank, not Amazon’s. Amazon doesn’t have access to the pin number, but your own bank need your pin to confirm your identity because they are authorizing Amazon card to direct debit your account every month for payment. Debit card PIN is your bank account PIN in most cases.

    Or you can just do it the old and slow way and ask them to send you the snail mail, in which you write your bank account info, hanko it, and send it back

  2. This is totally normal. If this is not done normally then anyone could just use yiur info to autopay their own credit card. That is authentication if you really are the user. Check the website if it is correct though. It should be your own banks website

  3. My credit requires your PIN to redeem their points online, despite the redeem page requiring you to log onto their portal using your account anyway. Makes no sense.
