Will Jaime be able to track your character? Absolutely
Is there any important tech on your character's person that Jaime would detect or that the Scarab would communicate with? David wears Tech-glasses of his own creation. Like Google Glass but far more powerful. Scarab could interact with this, and David would probably be happy to make sure to allow Scarab an open back door into the system.
Is there anything significant about your character that the Scarab would detect? Depends on how detailed Scarab's scans get. If highly detailed, there is some microscarring around David's heart and ribs his heart was literally ripped out once, and regrown by a high end healing mutant.
Does your character have any magic that the Scarab would read as energy output? No
Is there anything else about his abilities section that you think would be pertinent to your character? Nope
