Abstract: An electronic identification tag or card is indicated, which may be equipped with a rupture joint that has a vertical, diagonal, undulated, zigzag, meander-shaped or other type of design or pattern. The electronic identification tag or card may have two sections which may have a mirror-inverted design, and, in which, the same data may stored in the same manner. Integrated, embedded, or implanted memory or microprocessor chips may have the same structure, and one section of the identification tag or card is provided with punched holes for a necklace. Moreover, visually readable data, such as a personal identification number (PKZ), blood type (A Rh+), a nation and name (NN), may be introduced into is both sections. The electronic identification tag or card can be made of a very resistant plastic, glass, ceramic, or a similar material, the particular data carrier or memory device being embedded with or without intelligence in the form of a chip, magnetic strip or hologram.
