maybe wait until AFTER you have had a Philly cheese steak but before getting shot.

Exactly 
You PROBABLY don’t
It sounds like you are looking at the xMagic, which it a great first implant, just like the NExT, it just depends on your use case.
If you cant stretch to it financially, both with have you covered for most things RFID related.
This, Personally, I would reccomend a FlexM1
(i will link a relevant thread at the end)

A NExT would complement it nicely, if you were considering an xSeries with an LF chip.
Any questions, fire away
