Here at WebCreation UK we can support many of the leading payment providers into your website so you have the ability to select the payment provider that is right for you.
Many high-street banks have their own systems which are often convenient if you have an existing merchant account with them, some of the more popular include HSBC and Barclays.
If you are starting from scratch, then there are many payment providers who can easily set up an account for use online including Paypal and Google. Each of these can be configured to either forward customers to their own gateways or operate seamlessly with your site so that the customer does not even leave to pay. For the higher level of integration you will require an SSL certificate, which is a way of encrypting data, to accept payments.
