Just brought the Next chip implant, trying to copy iso1444-3a does this chip come password protected??
Yep, but just the config bytes by default, not the actual user memory:

Copy a work access card iso 14443-3A with a Chinese read write device but keeps saying write fail
The NExT is not usually the implant of choice for cloning HF credentials
Do you know what type of chip it is? Mifare classic or something like that? If you’re unsure, can you scan it with your phone using an app like NFC Tools or TagInfo, that should give you more info
Which cloner do you have?

You would need a different implant to get a full clone of that card, there are several available that would work if you’re interested:
xM1, xMagic, FlexM1, FlexM1 v2, FlexUG4
Any of those should be usable to clone a mifare classic card
Do you have an android phone by chance?

Yep Samsung, which chip do you recommend from above mentioned?
It depends on what you are prepared to do install wise and what you are hoping to achieve.
The X series are injectable with a syringe but have a lesser read range. The flex are much better when it comes to reading. All are good though.
I personally only have injectables as I don’t have anyone who can install using a scalpel. Mine work on most readers but maybes 1 in 5 readers won’t pick them up.
A flex is certainly safer in terms of it working on pretty much every reader.
However an upload of a scan of what you want to copy is a good idea to make sure you get the correct implant.
