A method and system track the life-cycle of a film unit (10). The film unit (10) has a unique identifier (42). A logical memory unit (20) is allocated to the film unit (10). The logical memory unit (20) is remote from the film unit. The logical memory unit indicates the identifier. After the film unit is sold, status data about the film unit (10) is sent to the logical memory unit (20) and recorded, when the film unit is used in an input unit (16). <IMAGE>
