Badges we design and build
Custom electronic badges for conferences and companies
Your event badge, designed and built end to end.
We design the board, write the firmware and the challenge, and build the badges ourselves. Conference badges are open hardware: your attendees get the repo, not just a lanyard.


Electronic Cats is an open hardware company from Mexico. Since 2018 we have designed and manufactured custom electronic badges for 20 conferences in 8 countries, including REcon, 44CON, BSides San Diego, EKO Party, DragonJAR Con and BugCON, and for companies like OXXO.
