One more "Which implant should I get and other dumb questions"

Yes. That is exactly what that means.

awesome, thanks

Now im wondering wither i should go for NExT on one side and xM1 on the other
Or xEM and xM1 on one side and xDF2 (or wait for the apex) on the other …

Unless you have a reason for a desfire chip I would wait for Apex. It is Flex only at the moment.

thanks for the input.
I do not have a use for the desfire atm, the only use i have is the T5577 and M1K …
The nfc would be to play with link and such … more and more leaning toward the xEM & xM1 duo, leaving the other hand for future use (Apex + xEM …) but the NExT is so tempting …

I dont see much implant on the inner wrist, any specific reasons for it?
any issue with wearing bracelets and watches with inner wrist implant?

I’m considering opening up the 32k ndef applet option again on the P71 chip now that deployment seems to be working properly… so you could have, in theory, a 32kB ndef container on an Apex… but more testing is necessary.


Currently in my L0 I have a Spark 1 in my R0 I have a NExT

Soon™ I will relocate my Spark 1, and I will be putting an xM1 and xEM into my L0

FOR ME, this will be an ideal setup, Across both hands in my Position 0’s it gives me
2 x LF emulators ( I can run 2 different modes and they are easily changeable )
Multipurpose HF ( NTAG216 )
Changeable NUID (Mifare “Magic” 1k)

In my opinion, the xEM and xM1 are a viable and very usable option, now you just need to decide on your other implants.
If it was me

xM1 + xEM

IMMINENT ™ , but no so imminent you should wait to place your first order


Remember you have other places you can put your implants

That’s awesome, this is only for the NFC Type4 section of the Apex right?
I thought the Apex had about 300kb for the applets …

Thats the combo and location im thinking … leaves room for whatever cool is gonna happen on L0 (and can always add an xEM there to complete the set …)

The NDEF applet creates a type 4 container on Apex, addressable using the standard NFC type 4 AID.

Actually that needs to be updated … the true available space for applets and user data is about 80kB.

Still trying to figure out which implant to got where (I’m probably gonna pull the trigger by the end of the month …)

So far I’m thinking xM1 and xEM in L0 for work access, but I’m starting to play with home access and having a fixed UID is becoming important.
So I’m looking at the xSIID

Had anyone ever used one on the top of the wrist/above the watch?
Any pro/con to know?

Otherwise I’m returning to the NExT and finding another stop for the xM1

xEM and xM1 in L0 and NExT in R0 is also my current installation, can confirm its pretty great if your readers are good enough to couple well with glassies. xMT in R-WATCH (?) position rounds out the set for me on the applications that needed further range.

Possible ones I’m considering for next steps are Apex and maybe flexClass in L3 and R3 positions.

Personally I’m not the biggest fan of the idea of a glass bump in my wrist, more a fan of flex implants there. I also avoided my left wrist since I didn’t want any trouble with my Apple Watch NFC.

Yeah, that sounds like a well thought out and usable setup. Thanks for the heads up om the xM1 & xEM positioning.

we will be Twinsies

xEM and xM1 in L0 and NExT in R0

I will splint between the 2 and tape them down whilst they encapsulate…

We will!
I just got my order # :grin:
Got the “ultimate” bundle and added an xEM and a HF x field detector to have 2 full sets.
Probably not gonna install the spark (I’m not installing something I don’t have full understanding of what it does…)

How long do you need to keep them splinted?
I was thinking side by side, along the metacarpal of each fingers.


This depends on your own body and the collagen production, if you are taking prenatals etc.

Depending on where exactly you are thinking of, you may not need to splint between them.

I was thinking L0 for the 2, one toward the index, the other towards the thumb.

But maybe that’s not the proper way to get at it

Some people do just that, in fact, I’m planning to get an xDF2 and an xEM installed in L0. But do keep any chips that run at the same frequency separate, this doesn’t apply to the xLED Field Detector as it’s just a light with no chip.

Also, there’s a X-ray thread and it contains examples of people with two chips in position 0:

Perfect, thanks for the confirmation.
The pla:

The spark may (probably) not get installed … I dont have a case use for it (yet?)

Ok, got my shipment today :grin:

But that brought up some wired questions …
I can’t read through all the packaging and the needle (as expected), should I try to read before injection to confirm proper operation?

Also, are the needle lubricated?

As a side note, is there any other applications of the Spark2 than the 2FA through vivokey?
Basically, what can I do with it?
I want to know what I can do with it before deciding to inject it or open the packaging and use the implant for testing …

Nope…Just trust that it will work.
We all did, The chance of getting a failure is extremely unlikely.
There are quite a number of threads and posts by people thinking that their implants are not working, but most, if not all are “operator error”, but you have been around long enough to know this.

Yeah they are, lightly, I havent had an issue with penetration, but more lube would make it even easier ( I have never used additional lube for an xSeries )

Are you planning on getting an Apex? If so, your Spark will act as a backup to your account.

So you are aware of using your account for logging in to the forum and Vivokey Forum, also if you have a wordpress site, you can do the same etc.
The Spark will also provide you another means of sharing contact info or url links.

Also this brilliant piece of work bu @pips

Heres the official webpage info

I expect, but cant gurantee, that when Apex is released, there may be a couple of functionalities that may trickle over.

I hope that answers your questions

Fire away if you have more

Surely will. Much stuff can be done with Sparks theoretically and VK promised to do what works, just that the login is different on Apex, tech wise.

At least everything that just requires a VK login will easily work with Sparks.

That said, much other stuff just can’t be done on Sparks, so it will always be very limited compared to Apexes.
