Choosing the correct tool for the job -- Implants and Desires

Great post and great attitude.
Many good questions,
Generally, it is easier for somebody to tell us what they are trying to accomplish / access. etc
Quite often, people buy and implant and then ask what they can do with it…
The tricky thing is, You on the other hand, are asking us “what you should get to do everything”

I can certainly give you my opinion. BUT It depends on a couple of things
How big are you willing to go?

If I wanted to be ready for almost any situation this is what I would get.

xSeries ONLY
NExT Implant
xM1
xSIID (Since you like Blinky)

Cryptobionic Identity
Spark 2

Size is no issue aka Flex
FlexNExT ( Not available just yet , WE ARE RE-ENGINEERING THE FLEXNEXT SO IT IS CURRENTLY UNAVAILABLE - But a FlexNT and FlexEM would be the equivalent now
FlextMT
FlexMN

Specialist

Payment
Payment conversion or Walletmor

Cryptobionic Identity inluding these
Vivokey Apex ( Available Imminently ™ )

___ ___ ___ ___ ___ ___ ___ ___ ___ ___ ___ ___ ___ ___ ___

And now to answer the rest of your questions

That is a question for Amal.
But from my observation on this forum, People like Blinky, just like you

:blinky_blue:
xSIID
Again, I think Green and Blue are the 2 most popular, if you go down this path, just be aware, you will have to consider the placement, as you will only be able to place this near LF implants.

My personal favourite, because it covers MANY options.
2in1 dual frequency
the LF chip is an emulator and it covers a lot of options,
the HF chip uses common ISO14443A plus NDEF capable

Personal preference and requirements
Flex - Bigger implant, better range, slightly more difficult to install
xSeries - Smaller, reduced range, easy install

Accidentally! I would say no, if you do things correctly then you should be fine, however, the Gen1 is the more popular.

I could keep rambling, but if you have any more specific questions, just ask
