static bar code header frame

+ +

Provides an implementation of the static bar code header frame specified in UIC IRS 90918-9 including:

+ +

    +
  • encoding of the data for creating a bar code
    • +
  • decoding of data from bar code content
    • +
  • support for the additional header information required with the TLB content
    • +
  • support for the TLB bar code content
    • +
  • support for the FCB content (using the UIC FCB implementation)
    • +
  • support for bilaterally on unilaterally defined additional content
    • +
