[0:06](https://www.translate.mom/transcript/AuQjfxm44nPa/en/can-bluetooth-mac-addresses-reveal-medical-implants?t=6) These networks are built to stay hidden, but to function, every Bluetooth chip has to broadcast its presence.

[0:13](https://www.translate.mom/transcript/AuQjfxm44nPa/en/can-bluetooth-mac-addresses-reveal-medical-implants?t=13) Take a single beep from a scanner app detecting an unknown signal in a room.

[0:18](https://www.translate.mom/transcript/AuQjfxm44nPa/en/can-bluetooth-mac-addresses-reveal-medical-implants?t=18) The app captures that raw transmission and extracts its forty-eight-bit digital license plate, a permanent code engineers call a MAC address.

So how does the app prove this specific signal is a medical implant? It isolates just the first twenty-four bits of that string to find the manufacturer's unchangeable hardware signature.

[0:41](https://www.translate.mom/transcript/AuQjfxm44nPa/en/can-bluetooth-mac-addresses-reveal-medical-implants?t=41) This exact prefix is called an organizationally unique identifier.

[0:46](https://www.translate.mom/transcript/AuQjfxm44nPa/en/can-bluetooth-mac-addresses-reveal-medical-implants?t=46) The app cross-references this prefix against a public database, exposing the actual hardware maker, like Nordic Semiconductor or Telink.

[0:54](https://www.translate.mom/transcript/AuQjfxm44nPa/en/can-bluetooth-mac-addresses-reveal-medical-implants?t=54) Finally, the scanner measures the signal's physical intensity to calculate exact distance. This proves the chip is mere centimeters away, operating inside the user's body. So what happens to that single mysterious beep from the beginning? It is now a fully identified medical chip,
