摘要： A security document, e.g. a banknote, is disclosed which carries a first magnetic security feature which is one of a predetermined set of features (for example, to indicate the denomination or value of the document); and a second magnetic security feature which is random and/or is unique to a given specimen document. A method of providing a security code for a document, e.g. a banknote, is also disclosed; this method comprises: (i) applying to the document or to a precursor of the document a first magnetic feature which is capable of being read by a contactless magnetic reader and which has a fixed magnetic signature selected from a set of magnetic signatures each of which is characteristic of a given denomination or other characteristic of the document, said first magnetic feature being applied to a predetermined location of the document; and (ii) applying to the document or to a precursor of the document a second magnetic feature which is capable of being read by a contactless magnetic reader and which is characterised by (a) its magnetic signature and (b) its spatial location on the document, wherein the second magnetic feature is such that either one or both of its magnetic signature and its spatial location on the document is effected at random at the time of its deposition.
