Capsule for guiding light and associated contactless payment device

A contactless payment device comprising:

• a capsule comprising a rim having an opaque periphery, which is interrupted so as to form at least four transparent portions;
• a support bearing a printed circuit and at least two light-emitting diodes disposed before a circular cavity made in said support;
• a ring having at least one recess on an inner periphery of the ring;
• at least one pin disposed on the periphery of said rim, within said at least one recess of said ring;
• said capsule being centered on said cavity of said support so as to be aligned with said at least two light-emitting diodes and said ring being positioned above said capsule which is kept free in rotation, said capsule being rotatable between at least two positions:
• a first position in which at least one pin disposed on a peripheral surface of said capsule is in contact with a first end of said at least one recess of said ring, and two of said at least four portions of said rim of said capsule simultaneously let through light coming from said at least two light-emitting diodes;
• and
• a second position in which said at least one pin of said capsule is not in contact with the first end of said at least one recess, and said rim of said capsule blocks the light coming from said at least two light-emitting diodes.
