PayPal is a digital wallet which means that we have an ecosystem built with consumers and merchants. When a merchant adds PayPal as a payment option to their site, we bring our 203 million (roughly the number at the moment) consumers to the merchant who can use the site with confidence having the trusted PayPal logos on the checkout page. We have seen an increase in overall ecommerce site conversion when we had merchants who added PayPal as a payment option with growing consumer confidence.
This consumer confidence comes from the highest level of security we provide to our customers which is also the second part of your question. PayPal has achieved PCI DSS (Payment Card Industry Data Security Standard) compliance certification under various programs and standards. We are committed to security as well as the protection and integrity of customer data.
