Finally got my order

Thanks for answer, I’ll definitely change my schedule and start avoiding ninjas from now on.

And today LF next wasn’t working again…
I’ve tried on 2 readers…
If it’ll be like that when I come back home I’ll see if xAC works and if not something is wrong…

Oh seriously? So it worked, then didn’t, then did again, now doesn’t again?

Yeah, I am so confused.

It doesn’t seem to be moving or anything

Okay, So I stand to be corrected here, but since you are getting intermittent faults… (as I type Amal just answered you, so good timimg) in my mind ( could be wrong ) it is either something you are doing or not doing
There is a loose connection between the chip and antenna, which would be unlikely because it is cast in Resin
What did you try and “read” it with?
Did you try XAC again?

I had no time to try xAC this morning I’ll as soon as I come back, so in around 10h form now.

I was just trying 2 door readers that were working yesterday.

hmm ok… it sounds like a cold solder joint. Basically the wire we use is coated and the lead free soldering process used to bond the wire to the inductor input on the chip must be hot enough to burn the coating off the wire and make a solid electronic connection, but sometimes the solder process is too fast or the heat transfer from source to target is not efficient and you end up with a cold solder joint which works but the wire is just sitting in a pocket of solder and not mechanically bonded… so it’s literally a loose connection that will work sometimes and if you jostle or jolt it, can stop working… it’s very hard to test for these situations because often times we test and it works… chips that fail to work we consider failed and remove, but if testing is passed we ship it… and maybe that connection works fine for a while but after normal use it can become intermittent.

We are working on ways to test for this, possibly by x-ray examination, but we need the testing method to remain cheap enough that the cost to produce doesn’t skyrocket.

For now let’s consider the NExT defective. Reply to your order confirmation email with this forum link and we will ship you out a replacement. Sorry this happened :confused:

I actually got replacement from last time I reported it wasn’t working.
Thought you know it and that’s why I messaged you about it started working again. So ofc new one isn’t needed.

But I have no idea how to approach this problem. As I said my access to professional is somehow limited as I now only one doing this type of stuff and his prices are a bit to high, but more important is fact that I don’t know if I’ll stand a removal without anesthetics :confused: and piercer can’t use them I think.

Ah sorry… so many messages and things going on at the moment I lose track… sorry… so to be clear you have a replacement already but haven’t had a chance to install it.

  1. make a pain management patch: take a topical lidocaine gel. A 4% solution or gel is common, and easily found in pharmacy… sometimes sold as “burn relief cream”. Check the active ingredients list. Also buy some waterproof plasters / bandages, and some medical tape. Put a generous amount of gel on the pad or gauze of the bandage and make sure it does not spill over on to the adhesive section around the perimeter of the bandage or it will not stick well to the skin. Wash the area really well with a basic soap with no scent. carefully place the bandage over the work site and ensure a clean seal all the way around the perimeter of the bandage. Finally, carefully apply medical tape over the entire bandage to completely occlude it (seal it). Leave it that way for 2 full hours. If you have been successful at keeping the bandage sealed and tight to the work area skin, you will have really good numbness… very nearly as good as injectable lidocaine.

  2. use a large gauge piercing needle to go in and surround the offending implant to remove it. By using a piercing needle of a much larger gauge, a piercer can easily cut all the way around the installed implant with the needle, and take it out like a core sample being taken from the ice in Antarctica.

  3. best practice is to place the new implant in a new location, not in the hole left by the old implant.


To be honest it’s the only location that would be useful. Left hand, recommended location.

I just mean not in the same hole… can be left hand just 5mm to the side of the hole.

Next does have 2 antennas right? One lf one hf? I just want to clarify that only lf doesn’t work.

Instead of pulling the faulty one out, would it be better to just call it a free xNT and then put the replacement NExT in your other hand? Saves you the trouble if you don’t have access to a professional.


I have NExT in left hand and xM1 in right hand so idk about the interference. I would have to have it in knife edge.
But it’s certainly a good idea.

It would be actually good for multi frequency readers, as I heard NExT can be tricky to use with those, if it’s possible to stop xEM from responding when it actually decides to work.

There are other places to put implants also, below is just a general “guide”, it is all dependant on your anatomy, make sure you do your research before you go stabbing yourself ( there many blood vessels and tendons to avoid ) but just so you know you have some other options… also doesn’t HAVE to be hands, but normally the most practical!

In reality, I should change the picture; Where it shows Orange and says OK, it should really be read as Okaayyyeeeeee, but you should actually look for somewhere green if possible.
Orange can be done, has been done but not really recommended. Red is still a definite NO NO

I have this “issue” BUT It is still workable, I have learned how to approach each individual reader, and now rarely get a

I am getting an xEM that will “solve” this “issue” but that’s not the reason for it.
( My NExT - xEM side I will revert back to EM mode for other projects, and my actual xEM will become my work dedicated T5577 )

Thanks, I still think the best place will be knife edge, the OK spots will be the best for eventual future flex.
Eventually between midand pointing finger.

Anyway is it even possible to disable the redundant faulty xEM? If I’ll ever have problems with multi frequency readers? It will be more convient as this xEM won’t be reliable working and not working in a few days cycle or so.

Jeez, soon I’ll be more robot than human :robot::smiley:

Not if it is a cold solder joint, like Amal suspects.

But hypothetically if you were going to get into it, you would re-solder the joint to repair it OR just put in an xNT, again,Not that it is possible.

I am not sure if I said it clearly, I don’t want to repair it, I know it’s not gonna happen. I would like to make it unreadable as it’s not reliable and will only mess up xNT read on multifrequency readers.

I am getting PM3 for xM1 so it wouldn’t be problem if I needed it.
