    Abstract: A dispenser with a replaceable cartridge containing a product to be dispensed, and a housing configured to removably receive the cartridge. The cartridge has a surface that is marked with a first marking, and the housing has a surface that is marked with a second marking. The housing is configured so that, when the cartridge is received by the housing, the first marking and the second marking together form a machine readable code that is detectable from outside of the housing.
