A dispensing system for dispensing a fluid material onto a substrate includes a jet dispenser configured to receive the fluid material therein, the jet dispenser having a jet cartridge operably connected thereto, the jet cartridge being configured to receive the fluid material from the jet dispenser and having a nozzle through which the fluid material is discharged towards the substrate; a camera configured to acquire a digital image of the jet dispenser; and a controller having a memory and a processor. The processor is configured to: identify, on the digital image of the jet dispenser, an identified pattern of features present on the jet dispenser; compare the identified pattern with a stored pattern, the stored pattern being stored in the memory; calculate the similarity between the identified pattern and the stored pattern; and provide an identifier value associated with the stored pattern.
