ım onur. Michael Ossmann He published a blog post called "toorcamp badge hacking". the problem I am experiencing is that ToorCamp's badge has an RFID-like feature. How can I make a simple circuit similar to this badge? And what's on this badge?

I'm not entirely sure what was on the badge, but that blog post says it was very simple: a coil made out of traces on a PCB, a capacitor (or two), and some LEDs.

You might also be interested in Kristin Paget's Shmoocon talk on a building a similar device, which goes into a great amount of detail about the theory of operation: https://archive.org/details/Be_Free_Little_Guardbunny

The badge's coil was center-tapped. Using a jumper you could (iirc)
shunt two of the taps together, retuning the coil. This allowed you
access to the two most common rfid bands, not just one.

If I run across my badge sometime soon I'll take some photos of it,
with a banana for scale.

I designed the badge and should have the design files around somewhere. I’ll try to get them up on GitHub sometime soon for people to play with...
