The speaker analyzes the Rocateq system by intercepting control radio signals, studying 2.4 GHz communication from checkout systems, and reverse engineering the device’s electronics. Techniques include RF sniffing, logic analysis between chips, and firmware extraction from the microcontroller. The talk demonstrates how to replay control signals and manipulate these wheels — even using a regular smartphone.
