All the info is actually on the DT product pages, the problem is people have to understand and know what they need/want before they purchase.
A lot don’t.
For example,
if you knew that you needed Mifare classic BEFORE you bought your NExT, then you would have seen
Sometimes people come to the forum and ask BEFORE they buy.
We then give them likely solutions, in your case, we would have pointed you to the xM1 and FlexM1 as @Equipter did above.
That’s part of what the forum is here for.
You seem to be more impulsive than research-y.
That’s not a bad thing, just know, before your next purchase, just ask and we will all do our best to answer your question so you can make an informed decision.
There was a possibility that your NExT could have worked, but not as much as an xM1.
And yeah, I’m glad you don’t have buyers remorse, the NExT implant is a great product
Are you going to implant a Thanos infinity gauntlet with your XSIIDs?
Don’t forget to share
Just FYI
