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.

A method of use of a dispenser, the dispenser comprising a housing configured to removably receive a replaceable cartridge containing a product to be dispensed, the method comprising:
- generating a machine readable code;
- marking the cartridge with a first marking, the first marking comprising a first part of the machine readable code;
- and
- marking the housing with a second marking, the second marking comprising a second part of the machine readable code;
- wherein the first marking and the second marking are positioned so that, when the cartridge is received by the housing, the first marking and the second marking together form the machine readable code.
A method comprising:
- providing a plurality of dispensers and a plurality of replaceable cartridges containing a product to be dispensed, wherein each of the plurality of dispensers is configured to removably receive at least a subset of the plurality of replaceable cartridges;
- marking each of the plurality of replaceable cartridges with a unique first marking;
- and
- marking each of the plurality of dispensers with a unique second marking;
- wherein the unique first marking and the unique second marking are configured so that, when one of the plurality of replaceable cartridges is received by one of the plurality of dispensers, the unique first marking and the unique second marking together form a unique machine readable code, wherein the unique machine readable code contains information that uniquely identifies the combination of the one of the plurality of replaceable cartridges and the one of the plurality of dispensers that are combined to form the unique machine readable code.
