"(47) Confidence in and convenience of online services are essential for users to fully benefit and consciously rely on electronic services. To this end, an EU trust mark should be created to identify the qualified trust services provided by qualified trust service providers. Such an EU trust mark for qualified trust services would clearly differentiate qualified trust services from other trust services thus contributing to transparency in the market. The use of an EU trust mark by qualified trust service providers should be voluntary and should not lead to any requirement other than those provided for in this Regulation."
