Abstract

The last years show an increasing application of white light holograms as security features for credit cards. The holograms raise the level of security and they prevent more or less fraud and counterfeit. Two different methods of application such as embossing on cards or incorporation in cards are described. The principal differences between the two methods i.e.; long production-runs versus short production-runs will be elaborated. Our own development of a step-and-repeat camera to produce white light holograms will be elucidated.
