This document describes and defines the basic structure of the identification data objects held on healthcare data cards, but it does not specify particular data sets for storage on devices. This document does not apply to the detailed functions and mechanisms of the following services (although its structures can accommodate suitable data objects elsewhere specified): —    security functions and related services that are likely to be specified by users for data cards depending on their specific application, e.g. confidentiality protection, data integrity protection and authentication of persons and devices related to these functions; —    access control services; —    the initialization and issuing process (which begins the operating lifetime of an individual data card, and by which the data card is prepared for the data to be subsequently communicated to it according to this document). Therefore, this document does not cover: —    physical or logical solutions for the practical functioning of particular types of data card; —    the forms that data take for use outside the data card, or the way in which such data are visibly represented on the data card or elsewhere.
