Overview
ISO/IEC 11693-1:2012 - "Identification cards - Optical memory cards - Part 1: General characteristics" defines the generic, high-level requirements and guidance for optical memory identification cards. It is intended for card manufacturers, card issuers, system designers and equipment developers who need to interchange digital information stored on optical memory cards. This part is generic to all optical memory cards and points to recording-method–specific parts for detailed physical, optical and logical requirements.
Key Topics
- Scope and purpose: Provides the baseline characteristics necessary for interchange of data on optical memory cards and guidance for developing equipment and systems that use them.
- Card construction and dimensions: References ISO/IEC 7810 for physical card size, thickness, corners and edges; establishes that additions (chips, magnetic stripes, embossing, signature panels) must not compromise the accessible optical area.
- Physical characteristics and durability: Covers contamination, bending stiffness and warpage (referencing ISO/IEC 7810/7816-1), UV exposure, resistance to chemicals and general durability. Default test environment and conditioning are defined (e.g., atmospheric pressure range and no condensation).
- Environmental limits: Specifies atmospheric performance expectations (including thresholds for gaseous contaminants and salt exposure) and test conditioning requirements.
- Accessible optical area: Defines the need to protect the portion of the card accessible to read/write optical beams; precise dimensions and locations are delegated to recording-method parts.
- Optical properties and logical data structures: Describes that optical characteristics, encoding, error detection/correction, channel coding and marking structures are dependent on the recording method and are covered in complementary parts of the standard.
Applications
ISO/IEC 11693-1 is useful for:
- Card manufacturers designing optical memory cards to be interoperable and robust in real-world environments.
- Equipment and reader developers who build optical read/write systems and need to ensure compatibility and correct access to the optical area.
- Card issuers and integrators (transport, ID, secure credentials, archival data carriers) planning system architectures that store and interchange data on optical memory cards.
- Test laboratories and quality assurance teams adopting the standard’s conditioning and environmental requirements.
Related Standards
ISO/IEC 11693-1:2012 provides the foundational framework so that different optical recording methods (linear, holographic, or future methods) can be defined consistently and implemented interoperably.
