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 &amp; didn't have any use for them. So that's why I decided to implement an NFC reader to my motorbike.</p><h3 >How did I get it implanted?</h3><p >I bought both RFID &amp; NFC chips from atwww.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</p><figure><img src=https://projects.arduinocontent.cc/bcbbb704-43d0-4d07-9a04-ee575c546046.PNG /><figcaption> </figcaption></figure><h3 >Supplies</h3><ul ><li >Arduino</li><li >RC522 NFC reader</li><li >5V relay module</li><li >LM2596 stepdown module</li></ul><h3 >Step 1: Building the hardware</h3><p >First thought was to use a Raspberry Pi, but that will be too much unnecessary powerful &amp; power-hungry.

Start Motorbike with NFC Hand Implant

I implemented an Arduino NFC reader inside my motorbike so I'm able to start and stop it just with the implant in my hand.
