RFID Tank Circuits

Описание: Here are some links to the GitHub, Dangerous Things profile, and Tindie shop of Hamspiced... the individual who first reached out and sent me some of these to play with! Thanks, man! 😊

If you are not familiar with resonant LC circuits (also known as tank circuits) then this brief but digestible Wikipedia page can give you the rundown...

https://en.wikipedia.org/wiki/LC_circuit

... they make use of a neat phenomenon, and the upshot for us in the RFID world is that circuits like this can act as something of a signal repeater even though they are very simple and have no power source of their own. While they don't technically "boost" an RFID signal, they can extend the range at which some credentials (especially finicky ones) can couple with an antenna, successfully talk to a reader, etc.

This video shows their operation and the effects of introducing one into the path of RFID communication. They can be helpful to folk with implant chips, as we demonstrate here, but they're also fun to play with using basic RFID credentials and typical tech, etc.

There's a good chance I'll be at BSidesRDU this weekend... come find me there if you'd like to tinker with these exact tools and more when it comes to RFID equipment.

Enjoy! 👍😁👍
