And here it is
Remember the caveat
Arrived a few of days ago, happy with that
As some people may be aware, I carry a T5577 card in my phone case
Seperately, I also made a Range extender and carried that inside my case
But that was too much crap in my phone case, So my idea was to get a 2in1 Card
Identify the location of the chips and antennas
( In my experience, HF Coils tend to run the premiter in a retangular fashion, and LF Circular and central )
Next, Fill a glass vial with acetone, and make a hotglue seal around the neck over the HF chip, flip upside down to soak the plastic in the targetted location.
Place the contraption on a galss platform ( so the acetone doesn’t eat through the surface it is sitting on )
Let soak for a couple of hours
Let soak a couple more
Check the underside for signs of it losing the battle
Peel away the hot glue and peel off the soft melted plastic from the card.
I SHOULD HAVE TAKEN A PHOTO OF THE CHIP BEFORE I REMOVED IT
Oh well 
Desolder the chip and replace with a 22pf capicator
Why 22pf
Strip wire enamel with soldering iron, and Solder said capicitor to the antenna wire
Fill the void with hot glue
Test
Phone (Samsung S21+)
Reading a full sized DF2 card
Without Extender= 35mm
With Extender = 42mm
Was it worth it? Probably not, But It may help some people if your phone is struggling to read your implant.
