VivoKey Spark

VivoKey cryptobionics use industry standard contactless NFC secure element chips, giving you the power of strong cryptography with just a wave of your hand.
The Spark is a tiny cylindrical cryptobionic implant just 2.1mm by 14mm. It comes in a pre-sterlized injection assembly, making it easily installed by any medical professional or licensed body piercer.

Typically installed into the squishy webbing between thumb and index finger, the Spark will enable you to do amazing things with just a wave of your hand.
The Spark cryptographically links you with your VivoKey Identity in a way that is extremely secure yet easy to use. It is your key to a new world of enhanced digital identity and convenience.
Configure your Spark and secure your digital identity using the VivoKey smartphone app. No chip programming or fiddling around. Plug-and-play all the way.
Easily share your VivoKey Identity when anyone scans your Spark with their NFC enabled smartphone. Don't feel like sharing? You can go to private mode with a single tap in the VivoKey app.
As the VivoKey platform continues to grow, so will your new capabilities. Authenticating online accounts, logging into your computer, and securing physical doors and devices are all features coming soon.
We've created the world's first cryptobionic implants, and securely linked them to the cloud with an innovative API. Developer kits are available upon request. We also love enterprise partnerships and integration.
Frequently Asked Questions
Is the Spark safe? What tests have been performed?
The Spark is made with the same materials and manufacturing methods that other, similar FDA approved implant devices are. Unlike those devices, the Spark has strong cryptographic capabilities. VivoKey is currently in the process of aquiring FDA approval for the Spark.
What is the expected useful life of the Spark?
The materials the Spark is made from will last many human lifetimes. The digital chip inside the Spark will reliabley operate and perform cryptographic functions for a minimum of 50 years.
How is the Spark installed? What about removal?
Discomfort
The amount of discomfort will depend on where the Spark is installed and if the professional performing the installation is able to administer any kind of pain mitigation treatment such as a topical numbing agent or possibly an anesthetic injection. Typically it is reported to be as mild as giving a blood draw sample at a doctors office or medical lab, however some report it being similar to a bee sting.
Removal
If you choose to have the Spark removed at a later time, the procedure is simple and can be done by any medical professional as an easy removal procedure in less than 5 minutes.
