When Brody examines the ID card found in the burned car, she disassembles the layers of the card to reveal the RFID chip. It is not necessary to open the card to read the RFID chip. She then uses a laser reader to identify the owner of the ID card. A laser reader is not compatible with RFID. RF or radio frequency is required to activate the chip which in turn emits a unique signal to identify the chip. Brody could have just held the card up to any proximity type reader at the Palermo to find the owner.
Tetraphosphorous decaoxide, or P4O10, is not a 'byproduct' of (the chemical reaction between) phosphine gas and oxygen, but the main reaction product. The more severe error here is though that P4O10, or P2O5 as it is more commonly named, is a product of a whole multitude of chemical reactions. Phosphine gas, while not exotic, would by no means be the first reactant springing to the mind of the chemically inclined. The first substance would indeed be elementary phosphorus, which also yields P2O5 when you burn it.
