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 or conducted over the telephone or by fax, as the information transmitted online is strongly encrypted using complicated logarithm combinations.
For these reasons we use the services of WorldPay. Their 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.
Any communication between you and WorldPay is also encrypted to the maximum strength supported by the your browser using 128 Bit SSL. You are also protected from fraudulent use of your card in a "card not present" environment, by your card issuer. The card issuer provides you the right 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. Worldpay also ensures that they stay up-to-date with the latest versions of any third-party code they use, and continually review their own proprietary code to make sure that all transaction remain secure.
PayPal is highly secure. They use industry-leading technology (such as SSL) to keep your information safe.
PayPal automatically encrypts your confidential information in transit from your computer to theirs using the Secure Sockets Layer protocol (SSL) with an encryption key length of 128-bits (the highest level commercially available). Before you even register or log in to the PayPal site, their server checks that you're using an approved browser - one that uses SSL 3.0 or higher.
Once your information reaches the PayPal site, it resides on a server that is heavily guarded both physically and electronically. PayPal servers sit behind an electronic firewall and are not directly connected to the Internet, so your private information is available only to authorised computers.
PayPal's state-of-the-art fraud models and proprietary fraud engine work together to help stop fraudulent transactions before they happen. In addition, PayPal stays at the forefront of security, developing many anti-fraud technologies every year.
With PayPal, you've got the industry's most experienced fraud team on your side. PayPal processes billions of dollars in payments each year, allowing them to continually perfect their anti-fraud protections. As a result, PayPal's loss rate is significantly lower than the industry average. They also work with federal law enforcement to catch criminals.
PayPal is committed to protecting the privacy of their users. When you send or request money using PayPal, recipients never see your bank account numbers or credit card numbers. They only see your email address, date of sign-up, and whether or not you have completed PayPal's Verification process.
