Hey! I got my first implant today, a white xSIID. Happy to report it went well, and I was able to read it and see that wonderful blink as soon as it was in! As I’ve been preparing to mess around a bit, I stumbled across some older forum posts mentioning some strange effects of the 2kb memory, and I mostly understand the mechanics behind it, and I think I understand what the issue is and why it happens, but I’m not sure I 100% understand what I need to do about it, if anything. I’ve got a PM3 Easy and I’ve messed around with my magic ring before getting the xSIID, (Got to help my dad out and make him a copy of his gym fob, big thanks to @Compgeek for dropping his solution after 2 months of nothing in this thread, it worked perfectly!).
So after looking around the forums and the product pages, I think that I should use the Dangerous NFC app to set up the tag before I go about doing much else to it? I’m not worried about any actual security measures, as I mostly just mess with Arduinos and the RC552 reader for that, and don’t have any access control that needs any security. I’m mostly just trying to make sure that I protect the tag from myself, so that I don’t accidentally do something stupid and brick/mess it up. My use (for now and the foreseeable future) is mostly just for fun, so I don’t need to do anything crazy with it. I will most likely just use TagWriter to throw in a link or plain text, etc., until I’m more comfortable with the proxmark and it’s workings, but I have it if I were to need it for anything. So should I use the Dangerous NFC app? Not worry about it and just write to it? Do something with proxmark? Any advice would be appreciated, and if there’s anything else I should know about before I think about writing to it, let me know! Thanks!
