For millions of people around the world, WorldPay is the way to pay - trusted and secure. An important part of The Royal Bank of Scotland Group, the 5th biggest banking group in the world, WorldPay payment solutions are trusted by thousands of businesses, big and small.

Security is probably one of the most significant concerns for both the shopper and the retailer during an online transaction. In reality, an online transaction is probably more secure than a card transaction in a shop 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, their 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 mumwantsone site to Worldpay are encapsulated using 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. Any communication between the shopper and WorldPay is also encrypted to the maximum strength supported by the shopper's browser using 128 Bit SSL.

WorldPay supports the full range of fraud-prevention methods including online transaction authorisation, cardholder verification (i.e. via Verified by Visa and MasterCard Secure Code), and Address Verification Service (AVS). In addition, WorldPay has developed several in-house fraud detection/protection tools that are designed to avoid hassle and minimise financial loss (including the WorldPay Guarantee which can protect you against financial loss due to fraud).
