The short answer is no, you will not be able to read it in the injector.
This has been discussed several times on the forum before, I would recommend having a bit more of a read then asking clarifying questions if you cant find anything 
anyway to answer your question in more detail:
It is possible to sometimes read the 125 kHz LF tags inside the injector due to the magnetic coupling but with the HF chips like the spark you will have no luck. The implant is actually stored in the needle which acts as a Faraday cage essentially. The skin effect also comes in to play.
