Infrared Data Association
     
         (IrDA) A non-profit trade association
        providing standards to ensure the quality and interoperability
        of {infrared} (IR) hardware.
     
        The association currently has a membership of over 160
        companies from around the world, representing computer and
        telecommunications hardware, software, components and
        adapters.
     
        IrDA typically uses direct infrared i.e. {point-to-point},
        {line-of-sight}, one-to-one communications.  The standards
        include: {IrDA Data} ({SIR}, {FIR}, {VFIR}), {IrDA Control},
        and {AIR}.
     
        Ports built to the above standards can be found in products
        such as {PDAs}, {Palm} devices, {printers}, desktop adapters,
        {notebooks}, and {digital cameras}.
