Yes the VivoKey forum is a private forum for VivoKey members only. The Spark can do basically what any implantable NFC chip can do… the UID serial number can be registered with compatible stand-alone access devices like door locks, gun cases, padlocks, etc. which only rely on the UID for “security”, as well as be configured to forward anyone who scans it with their NFC smartphone to another URL or to share your contact details with them.
Those are the most basic functions that are pretty commonly shared with any NFC implant. Beyond that is where things get interesting. The Spark is a cryptographically authenticated chip implant that works with the VivoKey platform that can accept crypto-challenges from the platform to validate actions like authentication, transaction authorization, etc. and we have an API to make those functions available to developers who want to integrate those actions (Authenticity API - VivoKey Technologies).
We also plan on offering various services to VivoKey members. The first of which is the private forum. We have several others in the works.
so in short, all the reasons you might want to implant a regular NFC chip are supported by the Spark… it’s the additional capabilities that exist now and will continue to grow that are the really interesting bit.
