Sites providing Payment Verification services should be reachable without credit

When activating, topping up or buying a goodybag from a sim without credit, the payment will fail if the bank requires the payment to be authorised a verification service such as Verified by Visa.
Sims without credit can visit giffgaff.com to set up the transaction, but if the cardholder's bank requires the payment to be authorised by a third party site, the payment will fail.
Currently, giffgaff allows sims without credit to reach paypal.com but bank verification services such as Verified by Visa are not presently reachable without credit.
For example, Visa uses subdomains of arcot.com to verify affected payments. Subdomains include secure, secure2 and secure4 but there may be others.
To ensure such payments do not fail, it is suggested that giffgaff should ask Visa, Mastercard and any other service providers for a list of their validation domains and make them accessible from sims without credit, in the same way that it has done for paypal.
