I have designed PN532 module with antenna(attached) 30mmX22mm to work with java cards. I wanted increase its range. is it possible to do by modifying registers or on software part.

i am using adafruit library.

My test result

with MIFARE classic the range is 3cm

NXP java-card J3A040 CL the range is 1cm

NXP daul interface java-card is less than 1cm

Hi Anmol Kohli,

Hope you are doing great, on software side there is not much you can do, since this device does not have a DPC ( Dynamic power control), maybe you can try to redesign the antenna of your reader to match with you tags antenna, a 1 to 1 design in order to improve the performance or play with the power of the antenna.
