1. A system for identifying objects and locating relative positions of objects comprisinga plurality of objects each carrying an integrated circuit storing data, each said object having an opening penetrating said object and an antenna loop extending around a circumference of said opening and said antenna loop being spaced from a surface of said object in a direction perpendicular to said surface of said object, said objects being freely movable within said system and relative to each other and being arranged in stacks or rows with axes of said openings substantially aligned, said antenna loops of objects in a stack being superimposed;

  • at least one reading/writing device for contactless reading of data from said objects, one of said at least one reading/writing device and each said stack or row being movable relative to the other of said stack or row and said at least one reading/writing device, said relative movement being in a direction parallel to said aligned axes of said openings to permit reading by said reading/writing device of data carried by objects in said stack or row; and

    means for correlating each position of said reading/writing device relative to said stack or row with data read from an object at said position to thereby define a position of each object and an identification of said object by the stored data.
