The secure element is a component of a contactless smart card incorporated into a contactless smart card device. The elastomer compliant layer is preferably a silicone constituent and the thin coat protective layer is preferably a fluoroelastomer or fluoropolymer constituent suitable for bonding to the elastomer compliant layer.
