First off, apologies for a starting a new post, I know there was a related discussion in 2020, but I hesitated to revive an old thread, and I do have some additional questions
After years of indecision, I finally pulled the trigger and got the NExT injectable. I had my NExT installed a few months ago, between thumb and index. No problems, minimal pain and swelling, with a week everything was healed. It is not visible, but by making a fist it can be felt.
The NFC side works. The keyboard wedge and smartphones read and write it without issue once I get everything aligned. It is a bit fiddly, I have to get it in just the right spot, unlike larger tags, but it works.
The issue is with the RFID side. It seems extremely weak. It took about 10 minutes to find a position that let the Proxmark3 Easy register even a modest voltage drop, but with some finagling and an extra hand to hold things at an angle I was finally able to clone a HID Proxcard II onto it and verify the read, so it technically works, but the issue seems to be that the signal is so faint that no reader I have access to registers its existence so it’s effectively unusable. I’ve tried it on 3 card readers at my office and none of them even acknowledge a chip is near, but admittedly they do appear to all be the same model. I have tried using the sensor tags to locate a sweet spot, but no joy with the tag so far. I have successfully cloned to other T5577 chips (rings, stickers, etc) and used them with this system so I’m confident it should work
From what I’ve read I think the tag was installed properly. Since I can feel it through the skin I’m assuming it’s not too deep or anything like that, so I’m just trying to trying to properly manage my expectations. I understand that the compact nature limits its range, but this is so limited it’s unusable. Does it require a very strong card reader? I have no way to get the building to replace the readers, so I’d have to find one that works and use it at home for a diy project. If that’s the case, any suggestions on a known-working reader for hobby use? Ideally something easy to interface with a raspberry pi.
I am unlikely to undergo the cost and discomfort of removal, so I’d love to find a practical use for it. Being a cyborg is much cooler if you can actually do something with your enhancements If I reset the T5577 back to EM, would the xEM Access Controller v2 be strong enough to read it? I also just ordered a Redbee reader on Ebay after seeing Amal’s video about it.
Finally, could I reasonably expect to have a reliable experience with the office card readers if I get the FlexEM or FlexMN? I feel like I may have played it too safe getting an injectable for easier installation at the cost of viable performance. I don’t know how much skin attenuates signal, and I’d love to end up with something functional
