An electronic badge (or electronic conference badge, electronic circuit badge) is a gadget that is a replacement for a traditional paper-based badge or pass issued at public events.[1] It is mainly handed out at computer (security) conferences and hacker events.[2] Their main feature is to display the name of the attendee, but due to their electronic nature, they can include a variety of software. The badges were originally a tradition at DEF CON, but spread across different events.[3]
Origin and development[edit]
Before the 2000s, the intersection between technology and wearables started to appear. These were founded in simple electronic kits, which focused on a basic understanding of electronics.
In the early years of the twenty-first century, electronics enthusiasts experimented with complex circuits and wearables. With the hacker and inventor community pushing electronic badges into the limelight. DEF CON, the hacker conference, was the turning point. The conference introduced electronic circuit badges as not only a means of identification and entry but also as collectibles, each badge intricately designed to be a piece of art. The early badges were simple and came with blinking LEDs. However, as the years passed, the badges became more complex with a variety of puzzles and features.
The mid to late 2000s was the golden era of electronic circuit badges. These badges became profoundly interactive and often came with puzzles, games, and challenges that fostered an unprecedented level of community engagement and learning. Each badge became a collectible, which was eagerly anticipated by attendees year after year.
In the 2010s, the educational sector began to perceive the potential of these electronic badges. STEM education, in particular, significantly consists of hands-on learning experiences from circuit badges. Students could dive deep into electronics, programming, and circuit design interactively and practically. Makerspaces, equipped with loads of tools and resources, sprouted worldwide, offering enthusiasts the freedom to create customized electronic badges that express functionality and creativity.[4]
In the late 2010s and early 2020s, the electronic circuit badges were combined with IoT by the integration of technology. Result in enhanced connectivity features allowed these badges to connect to the internet, other badges, and various devices, increasing interactive possibilities. The open source also created an environment where beginners could create complex and diverse badge designs.[3]
Badges Function[edit]
Electronic circuit badges are used at a wide variety of events, including hacker conferences, maker fairs, and corporate events. They are also used by educational institutions to teach students about electronics and programming. Electronic circuit badges can also be used for practical purposes. For example, some badges include features such as NFC tags that can be used to access doors or secured areas. Other badges include features such as
- Microcontrollers - which allow badges to run games and other applications.
- Sensors, such as temperature sensors, light sensors, and accelerometers - are used to interact with the environment.
- Communication devices, such as Bluetooth and RFID - are used to communicate with other badges and devices.
- Power management systems - allow badges to work optimally on a single battery.
- Some badges also include more specialized features, such as GPS receivers, heart rate monitors, and even Geiger counters.
