Currently in my L0 I have a Spark 1 in my R0 I have a NExT
Soon™ I will relocate my Spark 1, and I will be putting an xM1 and xEM into my L0
FOR ME, this will be an ideal setup, Across both hands in my Position 0’s it gives me
2 x LF emulators ( I can run 2 different modes and they are easily changeable )
Multipurpose HF ( NTAG216 )
Changeable NUID (Mifare “Magic” 1k)
In my opinion, the xEM and xM1 are a viable and very usable option, now you just need to decide on your other implants.
