Security or valuable document with at least two display mechanisms

Abstract

The invention relates to a security or valuable document with - at least first and second display mechanisms (118; 128), - a processor (102, 108) for controlling the at least first and second display mechanisms, - an interface (112) for supplying energy for the processor from an external energy source (114, 136).

Description

technical field [0001] The present invention relates to a security or value file (or security or value certificate) and a writing device for realizing write access to the data memory of the file. Background technique [0002] The prior art has disclosed many different forms of documents (or certificates) with integrated circuits. For example, such documents are mostly in paper-based form, such as electronic passports or chip cards, especially so-called smart cards, which can be designed with contact or contactless or with a dual interface (interface). [0003] The prior art also discloses wireless identification systems for various such documents, which may also be referred to as radio frequency identification (RFID) systems. Known RFID systems roughly comprise at least one transponder (or transponder, transponder) and a wireless transceiver unit. The transponder is also called RFID marker (Etikett), RFID chip, RFID tag (Tag), RFID label (Label) or wireless label; the wire...
