FIELD: beverage preparation devices.

SUBSTANCE: to enable the recognition of placement and/or type of consumable in a simple, foolproof and easily implementable way an embodiment of the system comprises light source (31, 301, 311, 321, 331, 341) for emitting light (35) to consumable (4a, 40, 50, 60, 70, 80, 90), light sensor (32 302, 312, 322, 332, 342) for sensing light (36) reflected from reflection element (42, 52, 63, 73, 83, 93) of the consumable to obtain a sensor signal, which depends on the position, orientation, fluorescence, phosphorescence and/or polarisation characteristics of said reflection element, and signal processor (33) for recognising placement and/or type of consumable based on said sensor signal.

EFFECT: consumable recognition system for recognising placement and/or type of consumable containing a food substance for the preparation of a beverage by use of a beverage dispenser.
