The present invention relates to a cosmetic device comprising: \u2014an end-piece comprising a base and at least two elements upstanding from this base, \u2014a body configured to receive the end-piece, \u2014a means of rotating the end-piece relative to the body about X an axis, in which the end-piece has a profile in cross section in a plane containing which varies during the rotation. Features of a first signal type and features of a second signal type are combinable to form a combined signal type while allowing existing blocks in the graphical model environment to process the combined signal type without modification of the existing blocks. The ATM is operable to receive a transaction authorization from the user’s portable electronic device, to examine the transaction authorization, and to dispense an item to fulfil a requested transaction associated with the transaction authorization, without the terminal preparing an authorization request to a remote computer.
