Hello all,
I wish somebody can tell me how to use PN532 RFID/NFC Shield read NTAG213's data like a plain text which is programmed by NXP TagWriter.
Best,
Greg

Re: PN532 RFID/NFC Shield read self programed tag
Our Arduino PN532 library only has limited NTAG support. Apparently there are a ton of edge cases in the various formatting options, and writing code to deal with all of them would consume all the available program memory.
A full computer like a RasPi running libnfc can do a lot more processing:

Re: PN532 RFID/NFC Shield read self programed tag
Hi Mike,
Thanks for the reply. But actually I am using Arduberry as an interface between Raspberry pi and the pN532 shield. So I am using like the following like provide https://www.dexterindustries.com/Ardube ... rd-reader/. Recently I figure out those information I programed into NTAG tag was located on after page 6 depend on the string length I programed into the tag it may extends into page 7 and 8 etc. Basically 4 character per page and some random unknown stuff like page 6 it always starts at nxxx(x will be first three character that I programed into the tag)
