Wow. Reading the bit about disabling the chip security makes me wonder what the point of a chip card is in the first place? All it takes is lifting the mag strip and altering it to declare that there’s no chip.
And the card schemes are mandating the issuers to keep track whether a card was issued with a chip and then reject authorisation attempts with a magstripe that claims "no chip" available.
That being said, in reality there are again and again still issuers who did not implement this and similar security measures [1].
