Abstract
An identity card contains a radioactive substance and information on the intensity of the radiation of said substance. When the card is used, for example in a banking transaction, the current intensity is measured and compared with the information on the intensity given on the card. If the current intensity and the given intensity agree, the card is to be considered genuine.
