I’ve been thinking around and realised we are almost to the point where an “universal access implant” could be achieved…
So thought of sharing my view on what is my “dream implant” at the moment, In hope others would either share enough expertise and interest that this might even become an actual DT product, or we just start sharing our implant daydreams for fun.
(In which case, given how much we’re prone to see a raise in crazy 2077’s implant Ideas, I’m happy for you to use this as a global dump, @Pilgrimsmaster. )
So what do I meant with “Universal Access”?
One single implant which can allow me to get access to multiple distinct RFID access control systems which are based on ID or NDEF alone.
Technically VivoKey and other solutions will allow us to reach that… but only when (and if) all the access control systems get updated to use that.
So how do I see this “magical” implant?
First challenge is the frequency. You need to allow both HF and LF to be used to access your chip.
Here we have multiple possible approaches, from dual-antennas to dual-chip a chip that automatically adjusts itself based on the frequency received.
So I’m not that bothered with it.
Then comes the response, Which needs to emulate the protocol and ID of other chips…
We already do have chips and systems very close to doing that. To the point we could easily think of a chip which we could pre-program to reply as either a HF ntag216 or as a LF T5577. Or even go dual-chip again.
So the Main challenge remaining… how to make it so that the chip knows that the LF on my flat door must reply ID AAAA, but the LF on my uni is BBBB and the LF at work is CCCC?? This is the main bit that has not been addressed yet.
Then I start daydreaming about a small enough GSM chip which could make one roughly accurate GPS call (potentially really requiring a secondary antenna) when near the reader’s field. Once it gets the response, it could match it against a table containing:
- GPS coordinate
- response protocol
- response ID/NDEF
So using an app I could edit that table to say "within 1 mile of my job, reply as this protocol with that ID, Within 1/2 mile of my Uni, reply like this other protocol/ID… and in any other (default) case, reply with this other ID (my home one)
Of course a GPS approach might cause too much delay, and have issues with size/antenna/necessary energy input…
Overall feels “just out of reach” at the moment…
But as I dubbed it, this is a place for dreaming with “almost there” chip tech!
