1. A portable terminal comprising:
a display screen and a camera, all housed in a rigid envelope forming part of the terminal, the rigid envelope comprising:
a first optical coupling with a region of the display screen,
a second optical coupling with a region of the camera, and
at least one optical channel extending along the rigid envelope between said first coupling and said second coupling,
the rigid envelope including a first internal reflective surface and a second internal reflective surface;
wherein the rigid envelope captures a signal transmitted by said display screen and reflects said signal via said first internal reflective surface onto said at least one optical channel, and reflects said signal via said second internal reflective surface to convey said signal and restore said signal at said camera,
the terminal further comprising an envelope breach detector for detecting a breach of said rigid envelope in response to an alteration of the restored signal relative to the transmitted signal, whereby the rigid envelope plays the role of a secure anti-fraud envelope.
