When my client does, there is one:

I've done as a guest and with an account. The site is using OPC.

What is that?
i have no control over those fields. square controls all of that.

what logic they use to determine which fields they need in order to successfully a charge a card is not something that has really interested me. but they do things differently based on where you are located, various risk factors, etc.

in memory serves me correctly, i believe in europe they ask for an additional field as well. part of the anti-fraud movement.

but for the most part anything within the square box is controlled by them and not by me.

best.
