A system for determining a hygiene compliance metric which indicates a usage of hygiene equipment, said system comprising: - distributed hygiene equipment (11, 12,..., 101, 102) arranged to dispense a hygiene consumable and/or to dispose of a hygiene consumable; - a tag (2, 2', 2") configured to at least transmit radio signals; - positioning equipment (110, 110') arranged to determine information on a position of said tag (2, 2', 2") by at least receiving radio signals from said tag (2, 2', 2"), and configured to determine information on a direction along which a radio signal was received from said tag (2, 2', 2"), including at least two angles of arrival of a received radio signal and information indicating a vertical height of a tag (2, 2', 2") for determining said information on a position; - and a processing entity which is configured to receive said information on a position of said tag (2, 2', 2"), wherein said processing entity is configured to define a usage zone and an opportunity zone (410,...) into which said tag (2, 2', 2") may enter, to define a rule, and to calculate said hygiene compliance metric based on said information on the position, said zones (410 - 460), and said rule, wherein the tag (2, 2', 2") is arranged to be carried by said user and the processing entity is configured to process said information on a position of the tag (2, 2', 2") in relation to the defined usage zone to determine a usage instance of a piece of said distributed hygiene equipment (11, 12,..., 101, 102) and the defined opportunity zone (410,...) to determine an opportunity in relation to a usage instance for, in turn, calculating said hygiene compliance metric, - distributed hygiene equipment (11, 12,..., 101, 102) arranged to dispense a hygiene consumable and/or to dispose of a hygiene consumable; - a tag (2, 2', 2") configured to at least transmit radio signals; - positioning equipment (110, 110') arranged to determine information on a position of said tag (2, 2', 2") by at least receiving radio signals from said tag (2, 2', 2"), and configured to determine information on a direction along which a radio signal was received from said tag (2, 2', 2"), including at least two angles of arrival of a received radio signal and information indicating a vertical height of a tag (2, 2', 2") for determining said information on a position; - and a processing entity which is configured to receive said information on a position of said tag (2, 2', 2"), wherein said processing entity is configured to define a usage zone and an opportunity zone (410,...) into which said tag (2, 2', 2") may enter, to define a rule, and to calculate said hygiene compliance metric based on said information on the position, said zones (410 - 460), and said rule, wherein the tag (2, 2', 2") is arranged to be carried by said user and the processing entity is configured to process said information on a position of the tag (2, 2', 2") in relation to the defined usage zone to determine a usage instance of a piece of said distributed hygiene equipment (11, 12,..., 101, 102) and the defined opportunity zone (410,...) to determine an opportunity in relation to a usage instance for, in turn, calculating said hygiene compliance metric,
