Security is probably one of the most significant concerns for both the consumer and the retailer during an online transaction. In reality an online transaction is probably more secure than a card transaction in a shop or conducted over the telephone or by fax. Information transmitted online is encrypted using complicated alogarithm combinations unlike these other methods that use standard medium coding.
The WorldPay Select payment gateway uses a combination of both established and innovative techniques to ensure the security and integrity of all sensitive data, protecting both the retailers and their customers.
All communication between the consumer and WorldPay is encrypted to the maximum strength supported by the customer's browser using: TLS or SSL (security). Our public web servers are certified by Thawte, a public Certificate Authority ensuring that customers and retailers alike can have confidence that nobody can impersonate WorldPay to obtain confidential information.
All communication between the retailer and WorldPay, including the details of the purchase 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.
Data storage on WorldPay systems, and the communication between WorldPay and the worldwide banking networks, is regularly audited by the banks themselves. We employ sophisticated firewall technology and other security best practises to ensure only legitimate access is allowed. We ensure that we stay up to date with the latest versions of any third-party code we use, and continually review our own proprietary code, using current best practice at all times.
In addition card issuers protect cardholders from fraudulent use of their card in a card not present environment, such as over the Internet or telephone. As the customer did not sign for the goods they have the absolute right to demand a chargeback if those goods didn't arrive or the card was used fraudulently.
WorldPay also insure all of our retailers against the risk of them going out of business. If one of WorldPay's online retailers goes into receivership WorldPay protects the cardholder by directly refunding any debits onto their card.
These two combined allow complete protection for a cardholder.
