it always does that... when your get to purchase screen and that box pops up, you can either re-enrol (which it said for me the first time i used it) or if your not bothered Your card should have protection on it anyway. If its natwest and you use online banking its the same password for your online banking
I had this with one of my cards, it only happens with some cards - it's an added security. I've found however that you can register while you're still doing your buying - I guess it depends which bank you are with.
However, all electronic payment calls (using either system) are diverted to the relevant bank for authorisation. So entering a 'Verified by Visa' code should take you order through to Capital One, which will confirm to the vendor that it's the correct code for that card.
Thanks everyone! Pea....thanks for that link with Capital - just registered now.....gone back to the payment page and my shopping basket is now empty ...have to start all over again.. good job there is nothing to watch on the tele !!!
