Hey Buddy, Quite a lot to unpack there, But I think most of it should be easy to answer
In fact, I think I can answer it pretty easily. with only 1 implant (2 options)
I actually think this is your best option, and not overkill
I think you could get SOME things to work with other options, but if you want it all to work, just save up the money.
Do it once and do it properly
( the only alternative that would do everything you want is the FlexSecure, effectively the same, but it is not built around Fidesmo, and there are pros and cons to that )
Easy,I have around that, if not more on my ApexFlex
I use KeePass in conjunction with my ApexFlex
You could easily do that in the NDEF records ( upto 16kb i think ) and you could encrypt / decrypt this using 3rd party PGP
Here’s some explanation
No problem whatsoever
VivoKey Apex Flex and FlexSecure can do this
So we generally refer to the glass capsules as xSeries, they come preloaded in a syringe.
They are similar to, but safer than a pet implant chip
heres more info
The Flex come in a range of shapes and sizes, but, the term flex actually refers to the encapsulation material, the implants are not particularly flexible, more like semi rigid.
They “narrow” flex normally comes with a custom needle, or can be bought seperately, whereas the “Disc Flex” would require a scalpel for the install
The VivoKey Apex Flex and FlexSecure I am recommending are the “narrow flex” type, but there is also a ApexMega (“Disc”) with extended range, and the Apex Spectrum “Disc” with LEDs and I believe slightly reduced range to the Mega ( This one MAY become available again shortly)
Heres some more info on the Flex
Understandable, we are here to help, but also the forum search function works very well.
also some of the Primers, Info and Wikis may be of help to you.
Heres a good “all rounder” to get you started
I hope what I have given is of use to you, remember, it is mostly just my opinion, so continue to do your due dilligence, and ask questions if you get stuck
