You’d want to look at NFC implants if you want an implant that will work with almost every phone.
The first two chips that come to mind are the NExT and the xSIID.
The NExT contains two chips but is a single implant; an NTAG216 for the NFC side and a T5577 for the low frequency RFID side. While you’d be only using the NFC side at first, having an LF chip could potentially make your life easier when you start to add RFID to your home.
On the other hand, the xSIID is a high frequency NFC compliant implant that lights up. DT has a few bundles that include both a xSIID and an xEM in case you also want to get the low frequency functionality but you’d be looking at two implants in this case.
No, you’ll have to get at least two implants to get the three functions.
If I could make a recommendation, as something I failed to do early on, read read read!!! And then READ some more! Figure out exactly what you want to do, and what the priorities of everything you want your implantS (yes I almost guarantee you’ll end up with more than one) and you’ll save yourself a lot of time and heartache. And, probably money as well.
This is an awesome community! Ask away and welcome!!!
I think a better question to ask is this: what is your use case? There’s a large number of people, myself included, who wanted to do X with an implant, and got a chip that it turned out didn’t do what I wanted it to (in my situation, I needed a flexClass and ended up getting an NeXT). What do you want to do with it? If you want a way to have someone scan a business card or something small like that, an XSIID or a NeXT is a great choice.
