mfrc rc522 and ndef messages

hello,

I am new in arduino, and I am trying to read mifare card that have a stored a text, or number using ndef

can't make the rc522 mfrc make to read these text, I get other details like the uid of the card, but i would like to get the storred message.

my project have 4 mfrc rc522 reader and once on 10 min it makes a loop and reads all the rader and cards that are on the reader,

how can I read the storred message???
how can I store message with mfrc rc522 ????

PS the storred message's on the card are made with PN532 reader/writer and ndef library, does ndef library is compatible with rc522???

thanks
