I have to admit I find it pretty amusing this is news. About a dozen friends and I have had these for 4+ years, voluntarily. I no longer carry any traditional metal keys and have modified my front door, vehicles, etc to open via my implants. Friends even upgraded 2 vending machines at our hackerspace to work with them. In addition to access, I use one to store master encrypted backups of files I might need access to in a pinch and the other I tell everyone contains a vcard with my contact info, but really it just auto-launches rickroll on their phone when they tap it. The tags are all r/w and I can update them as I like from my smartphone. In a couple weeks I am getting a temperature sensor installed under my arm designed for animals. While temperature is not a super exciting sensor, it paves the way for more complicated ones in the future and I can see how it holds up over time. My next after that is an HID ATA5577 tag that I can use to clone the HID door cards of most offices. Once beta units begin to be produced I plan on getting a Vivokey installed which covers the typical use cases of a Yubikey and will allow me to do 2FA, ssh, password management, and cryptocurrency transactions from my body as well.
