In the DEF CON 32 talk "Psychic Paper: Making eink access badges accessible for anyone," Joshua Herman, also known as Zitterbewegung, unveiled a novel approach to physical red teaming and social engineering utilizing **e-ink** and **e-paper displays**. The presentation detailed how these low-power, non-emissive screens could be leveraged to create dynamic, reprogrammable identification badges, effectively mimicking legitimate access credentials in real-time. This technique represents a significant evolution beyond traditional static, printed badge counterfeits, offering a more adaptable and believable method for gaining unauthorized physical access.
