Verified by Visa is totally broken

My bank uses Visa credit cards. Visa has just rolled out a new "Verified by Visa" (VFV) system, which is supposed to be more secure.

In fact, VFV relies on XSS, random, unrecognisable third-party sites, and a generally woeful user experience which completely goes against security best practice.

There is background here: The 'Verified by Visa' fiasco ... courtesy of ANZ

In my case, thank fuck I was using Firefox with NoScript, for just look what it detected:

[NoScript XSS] Sanitised suspicious upload to [] from []: transformed into a download-only GET request

What the hell is ""? Why is at least WorldPay not processing this? Who authorised some random third-party site to access my credit card AND bank-specific security questions? And why the FUCK does it all rely on dodgy cross-site scripting to work?!?

All extremely shoddy, and designed to vapourize human confidence in online shopping. Well done Visa, you utter fuckwits.


  • Quelle coincidence! This very day I emailed to tell them what a shower of shite I thought their Verified by Visa system is (my current account comes with a Visa debit as standard). I didn't have all your technical geekery to back up my assertions, but hopefully the sheer force of my invective might prove persuasive.

  • I agree, its total rubbish. Had to implement it in booking engine at work. Conversions totally dropped off. Natwest VISA doesnt appear to have it enabled at the moment though.

  • Yes the same thing happened to me.
    I tryed to buy items from a shop that used RBS worldpay. So I canceled my purchase. Sent them an email that they should offer other payment options. I am not giving my exp date and codes to strange sites.
