NExT RFID + NFC Chip inquiry

How does this chip would work if you have a reader that can read/write both125kHz and 13.56MHz would they read/write the same time? Anyone has experience with it? Does it double read/write especially for UIDs using it for password/security purposes etc?

I would imagine you could control the reader to ensure it is only interacting with one chip at a time… assuming you have that capability.
