use a 'WorldPay payment system' which ensures that all sensitive
information sent by you is securely
transmitted when you place your order.
In reality, an online transaction
is probably more secure than a card transaction in a shop or conducted
over the telephone or by fax, as the information transmitted online
is strongly encrypted using complicated logarithm combinations.
The WorldPay payment system uses a combination of both established
and innovative techniques to ensure the security and integrity
of all sensitive data. Furthermore, our public web servers are
certified by Thawte, a public Certificate Authority, ensuring
that both the shopper and retailer can have confidence that nobody
can impersonate WorldPay to obtain confidential information.
The transfer of the purchase details from the retailers site
to Worldpay are encapsulated using our own encrypted and digitally-signed
protocol. This uses a combination of standard methods such as
PGP, RSA and MD5 to ensure that the information passed is secure
and tamper-proof via SSL.
Security for the Shopper
Any communication between the
shopper and WorldPay is also encrypted to the maximum strength
supported by the shopper's browser using 128 Bit SSL. Shoppers
are also protected from fraudulent use of their card in a "card not present" environment,
by their card issuers. The card issuers provide the right for
shopper to dispute a transaction if the goods/services did not
arrive or if the card was used fraudulently.
Data storage on WorldPay systems, and the communication between
WorldPay and the worldwide banking networks, is regularly audited
by the banking authorities to ensure a secure transaction environment.
We also ensure that we stay up-to-date with the latest versions
of any third-party code we use, and continually review our own
