It's an additional layer of security protection when consumers trade online and mostly used with online traders where consumers are paying for part of a product, such as a subscription or, in our case, where a balance is due on a product such as our A Weekend Away With... events.  As you proceed to the payment page your bank or card issuer, if they are signed up to SCA, will send you a text message, either as an SMS or via an in-app alert, asking you to authorise the transaction.  Your bank/card issuer will contact you when they are SCA enabled.   

The big and immediately noticeable change is that the site is much more mobile device friendly.  Where as the previous site was "mobile responsive" meaning there was mobile version of the desk-top site, V4 has been designed for the mobile user.  Things like images, sign-up forms etc should now fit on your mobile device and you should only need to scroll down to see an entire page.  In particular, our forthcoming events listing is much easier to read than before.  

V4 will enable us to have a VIP Club area, which, although the previous site gave us the same, it was very cumbersome to use and looked horrible. 

The new site will also enable to us to have cute new features, some of which we can have hosted on our servers, or others, which requires specialist technology, can be hosted elsewhere but available here, such as the mosaic image below.  The image in terms of space it takes up on a server is huge, so its hosted on a specialist image server. If you scroll your mouse over the image you'll see a thousand small images to make the mosaic picture.
