Does any one have an up to date sketch program code that works with an Arduino uno R3 with a NXP PN532 NFC/RFID module?

I am trying to build a security system, being able to use multiple Mifare cards. I have not been able to find one that is up to date and compiles correctly. Please help. Thank you in advance.

finding what ? a full code working or an example on how to use the NXP PN532 ?
(there is the Adafruit PN532 library you could use and they provide plenty of information in their tutorial)
