Alternative places for the Spark



Just bought the Spark and I’m curious to know what alternative places to install in the body beyond between fingers. I’m a Jiu-Jitsu practitioner and I’m worried it may not be the best place.

Thanks :slight_smile:


Consider your use cases now and in the future… can you place it in a location so it’s not overtop bone, not going to get kicked or jabbed, and still be able to manipulate it to present it to a reader, door lock, or read with your phone?


I had no room between my thumb and index fingers as I have chips with the same frequency there.

So I put mine in the forearm.

Procedure was same as always, maybe a little more bruising.
