1. A method of weighing one or more objects, comprising the steps of:
recognizing, on a weighing platform of a first scale or within an object recognition area of the weighing platform, at least one of the one or more objects; and
weighing, on a weighing platform of a second scale, a set of the one or more objects;
wherein:
at least one first object and at least one second object, different from the first object (collectively, the “different objects”), are recognized sequentially in the recognizing step;
the different objects are sequentially recognized on the weighing platform of the first scale or within the object recognition area of the weighing platform, and
a set of the first objects and a set of the second objects are weighed sequentially in the weighing step, either according to a sequence in which the different objects are recognized or according to a pre-set sequence; or
the different objects are sequentially recognized on weighing platforms of different first scales or within object recognition areas of the weighing platforms, and
sequentially weighing sets of the different objects in the weighing step either according to a sequence in which the different objects are recognized or according to a sequence in which the first scale weighing platforms or the object recognition areas thereof are arranged.
