What credit card transaction requires a PIN? Those are strictly for

All UK transactions.

Not actually come across any contactless credit cards in the wild yet.

Barclays. Both debit and credit cards.

On-line you need a different PIN, aka a security code.

That is in addition to supplying the 3-digit code on the back of the
card (without which you won't get as far as the password challenge
which cannot be all-numeric) and the requirement for goods to be
delivered to the registered address.
