We found that when placed under one of our replacement iPhone backs, the tag didn’t read, so we fiddled with tape and paper until there was enough air space between the metallic bulk of the phone and the RFID antenna.
One post-it note and four layers of packing tape later, the tag scans just fine from within the back of the iPhone, even with 4G and wifi turned on.

I wonder if you could lay the antenna and module down on a GelaSkin and then apply that to the phone. Hopefully GelaSkins are going to RF transparent enough…
It read fine even through the metal of the stock iPhone back.
However, though the back seemed to close fine on the pieces of the keycard, it caused the glass to bow slightly and the glass eventually broke when the phone suffered a light impact.
I’m going to try again with a custom wound antenna and Kapton tape.
have a friend who’s on a project and have an issue with RFID tag applied behind and android phone. RFID reads fine on a close contact reader but prevent the tag from being read on a “gate” reader.

I did a very similar thing with the keycard to my workplace a while ago.

Cool, I will try this with an Izmır kentkart and see how it works.
did you tried it on a “long range” reader?
