NFC antenna amplifier/Resonance Circuit project

Is there a way to test the current draw from the acr122u just sitting on the desk by itself, and then place the repeater sticker overtop and see if that affects current draw of the reader wlby any significant amount?

I’m trying to confirm that simply placing the repeater overtop the reader antenna will not increase power consumption by any significant amount. This is important to establish for battery powered devices like door locks etc.
