I am working off an Arduino Uno with an AdaFruit PN532 NFC/RFID shield. The goal is to have a shoe box, with a false bottom. Under that false bottom would be my prototype, which I hope will be able to detect any MIFARE tag that is in the box, above the false bottom.
The range obviously for these devices is practically touching, but I was was wondering if there is anyway to extend the reach of the NFC/RFID shield, so that the entire false bottom of the box could act as that antenna.
