Abstract

Documents, e.g. cheques, have visually and automatically readable regions of defined shape denoting the authenticity and value of the cheque, and are designed for protection against forgery and for economical processing of ordinary and guaranteed cheques by elimination of manual coding after issue. The region contains a first substance undergoing a physical or chemical change under the effect of pressure. A second substance spreads the effects of the first partial physical or chemical change over the entire code region. The two substances are applied in microscopic capsules. The capsules contg. the first substance also contain a substance capable of dissolving the capsules contg. the second substance.
