Syntax

'Declaration
Public MustOverride Property MediumId As String

public abstract string MediumId { get; set; }

public:
virtual property String^ MediumId {
    String^ get () abstract;
    void set (String^ value) abstract;
}

/** @property */
public abstract String get_MediumId ()

/** @property */
public abstract void set_MediumId (String value)

public abstract function get MediumId () : String

public abstract function set MediumId (value : String)

Remarks

The medium identifier is information (manufacturer’s serial number, and so on) to specify the card uniquely, and its content depends on implementation for the card. The following methods are processed to the card with the medium identifier specified by this property:

• AddValue

• BeginDetection

• CancelValue

• ReadValue

• SubtractValue

• WriteValue

The application can specify the card to be operated on by setting the medium identifier to this property before the method call is issued. Setting an empty string ("") for this property means the operation can be performed with any card.

The medium identifier of the card is set when the method that have relation to the card succeeds.

This property is initialized to an empty string ("") by the Open method.

Thread Safety

Any public static (Shared in Visual Basic) members of this type are thread-safe. Any instance members are not guaranteed to be thread-safe.
