Abstract
A security card is disclosed which comprises a laminate of a flexible glass layer and a support, characterised in that the glass layer has a thickness of not more than 350 &mgr;m. The thin glass layer has sufficient flexibility to allow substantial bending of the card without causing breakage of the glass. In addition, the glass layer acts as a security feature because delamination in order to falsify information stored in the card is very difficult without breaking the glass. The glass is also an efficient barrier layer protecting the information stored in the card from mechanical damage and from degradation due to permeation of gases such as oxygen or water vapour.
