MasterCard SecureCode / "3D Secure" or whatever they call it, has been active on my card for many years and I never had any problems whatsoever. Always worked like a charm.. And the upside, nowadays I don't worry anymore about anyone storing my CC number on their unsecured servers.

I think 3D Secure only prevents doing transactions without double auth in "3D Secure enabled" online shops. In the shops that don't have that implemented, the transactions can go through (though probably those shops pay higher provisions).

Correct. The payment gateway usually has a setting to enable/disable 3D secure as a feature.

You also get a failed transaction report, some people can have 4-5 goes before giving up on their purchase. Sometimes to countries somewhere abroad the customer gets a form to fill in to apply for having this extra check on their account (because there is no 3D secure in the country where they have their card registered or it is not customary to use it).

It would be nice to use 3D secure as an extra feature, and, as a retailer, set it on a case by case basis, e.g. to an order that is for somewhere overseas or over a certain value.

In the UK a fraudulent order is a fraudulent order, as a retailer you are on your own dealing with it. Putting someone's card address in Google Street View and seeing how big their house is often turns out to be a good way of deciding whether to 'ship' or not.

Address verification is a 'soft fail' if you want it to be. It will compare the address by numbers, so someone entering 'Flat 2' in the primary address line will fail the system if the address is actually 'Flat 2, 34 Church Street' as '34' is expected for the match.

There is no system guaranteed to work, except Paypal, that you pay for in fees.

These matters aside, the system of swipe only in the US just gives most people in the UK scary feelings.

Having lived in the UK for 3 years, I'm not sure anyone's "house size" over there is a good indicator for, well, pretty much anything ;D
