Paper Abstract

The widespread use of embossed holograms on credit cards has brought with it a huge boost of interest in holography in 1984.It is however easier to produce a counterfeit copy of these holograms able to deceive a busy shop-keeper than was originally realized by the credit card industry. The reason for this original lack of awareness is curiously because most holographers had been overlooking a phenomenon that they probably had all seen and which has existed ever since the first reflexion holograms.
