Abstract: Disclosed are a method of weakening an outline in a thin plastic card and tooling for performing the method. The method may include several operations, including a go punching step by means of a go punch presenting a solid shape substantially identical to the outline and suitable for punching the thin plastic card along a go direction against a die presenting a hollow shape substantially identical to the outline and in alignment with the go punch in order to be able to receive material pushed by the go punch, and a return punching step by means of a return punch presenting a solid shape substantially identical to the outline in alignment with the go punch and suitable for punching the thin plastic card along a return direction opposite to the go direction. Also disclosed is a thin plastic card including at least one outline weakened by such a method.
