Remarks

A designator assigned by the ECE institution that uniquely identifies the CheckBackImageData. This designator could be a key that would be used by the creating institution to located the unique associated image, or it could provide a full access path and name that would allow direct external look up and access of the image. For example, this could be a URL.

The size of the array is controlled by the CheckCount property.

This property is not available at design time.
