Start Motorbike With NFC Hand Implant

Why I even have an NFC chip implant in my hand?

I'm working as an IT support for a luxury hotel, so there is a lot of doors I need to open every day with a card. That's why I decided to put a 125khz RFID chip inside my hand. Unfortunately, my choice was wrong because we have NFC readers there actually. So I put an NFC chip implant to my other hand. Unfortunately again, I find out our system is not supporting a Mifare Ultralight C chips, what I have in my hand, so I end up with two chips inside my hands & didn't have any use for them. So that's why I decided to implement an NFC reader to my motorbike.

How did I get it implanted?

I bought both RFID & NFC chips from at www.dangerousthings.com. It arrived in a pre-sterilised package with a syringe with a loaded chip. After I just went to the first tattoo studio (shoutout to Trilogy Reading). Was it painful? I would say... 3.6, not great, not terrible :D

Supplies:

Arduino

RC522 NFC reader

5V relay module

LM2596 Stepdown module

Step 1: Building a Hardware

First thought was to use a Raspberry Pi, but that will be too much unnecessary powerful & power-hungry. So the Arduino was the right choice. First I made it work with Arduino UNO, but then made it smaller with Arduino Pro Micro. The connection was pretty simple, few cables & NFC reader was up and running.

Step 2: The Code

I used an AccessControl code example from RC522 Arduino library from Github & made a few small changes.

The only change was to make it behave like a toggle switch. Because when I start the bike I want to leave it started until I want to turn it off.

You can download the code here.

Step 3: Building It Up

After I just added a 5V relay module to connect to key ignition wires & LM2596 Stepdown module, because motorbike battery is 12V, but we need 5V. In the video, you can see a timelapse of the whole process & final result. Works like a charm.

Of course, I still need to use a key to open the fuel tank or lock the steering, but for starting/stopping engine, it's perfect.

    Amazing! Insane, but awesome. Since you've got the RFID chip as well, why not put an imobiliser keyed to that on the other handlebar? Thanks for sharing this: it is truly wonderful :-)
