Defcon's new badge is a security key you can see inside
Defcon's 2026 security badge doubles as a programmable hardware token with a transparent design, allowing attendees to inspect and modify its internals while retaining full functionality.

- Defcon 2026 badge is a transparent, programmable hardware security token that allows physical inspection and modification.
- The badge remains fully functional as a security key even after internal changes.
- This design aligns with Defcon's focus on interactive security research and hardware hacking.
- The transparent design serves as an educational tool for understanding security token internals.
Defcon, the annual hacker conference, has unveiled its 2026 security badge as a transparent, programmable hardware token. Unlike traditional opaque badges, this design exposes the internal circuitry, enabling attendees to visually inspect and even modify the device's components. The badge retains full functionality as a security key, allowing users to continue using it for authentication purposes even after physical alterations. This innovation reflects Defcon's long-standing tradition of hands-on security research, where hardware hacking and reverse engineering are core activities. The transparent design also serves as an educational tool, making it easier for newcomers to understand the inner workings of security tokens.
Provides a tangible platform for hardware security research and reverse engineering.
Highlights innovative approaches to security token design and transparency.
