It details and commands depend on the tag you are trying to use, but in general it is as follow:
- break teh encryption on the original tag
- read the original tag
- dump the data from the original tag on teh PM3 or computer
- write dumped data to a fresh tag
(- confirm the new tag has the proper data written on it)
