How can I change my physical card PIN number?
You can do this at compliant ATMs
PIN change is supported and available to the user at ATMs only. This option is usually only available to EMV Compliant ATMs which are typically found at Banks and some Supermarkets.
When you present the card to the ATM and enter the PIN, there should be a PIN change option. If the ATM has this option then PIN change should be possible.
