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.

I know they exist, just haven't come across any.


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

Which is what I was referring to.

Hardly a "PIN" as it is stamped on the back of the card and is mainly
concerned with "cardholder not present" transactions. It is
deliberately visible as it does not otherwise appear in the
information contained in/on a card and requires use of a Mk.1 eyeball
to read it thus cannot be determined by a magnetic stripe reader or
from discarded undercopies if anywhere is still processing cards the
old-fashioned way.

(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.
