//This example show how you can get Authenticated by the NTAG213,215,216 by default the tags are unprotected in order to protect them we need to write 4 different values:
// Using mfrc522.MIFARE_Ultralight_Write(PageNum, Data, #Databytes))
// Using mfrc522.MIFARE_Ultralight_Write(PageNum, Data, #Databytes))
//1.- we need to write the 32bit passWord to page 0xE5 !for ntag 213 and 215 page is different refer to nxp documentation!
//2.- Now Write the 16 bits pACK to the page 0xE6 use the 2 high bytes like this: pACKH + pACKL + 00 + 00 after an authentication the tag will return this secret bytes
//3.- Now we need to write the first page we want to protect this is a 1 byte data in page 0xE3 we need to write 00 + 00 + 00 + firstPage all pages after this one are write protected
// Now WRITE protection is ACTIVATED so we need to get authenticated in order to write the last data
//4.- Finally we need to write an access record in order to READ protect the card this step is optional only if you want to read protect also write 80 + 00 + 00 + 00 to 0xE4
//After completeing all these steps you will nee to authentiate first in order to read or write ant page after the first page you selected to protect
//After completeing all these steps you will nee to authentiate first in order to read or write ant page after the first page you selected to protect
//To disengage proection just write the page (0xE3) to 00 + 00 + 00 + FF that going to remove all protection
