Abstract: A coding for a medical disposable item is proposed comprising at least one information component in encoded form. Associated encoding methods and devices, and associated decoding methods and devices, are also proposed. The coding generally comprises an optical information component comprising one or more fields filled with a gray-scale value up to a certain degree of filling. Each gray-scale value and degree of filling are associated as a value pair determined as part of a code generated to correlate to an information component desired to be applied to and conveyed from a medical disposable item to an associated device that utilizes such items.
