Thanks for letting us know that one.
I dis-arm the pay way on our cards, it is easy to do it.
The best way is to have a fine tip felt marker pen handy, even dry wipe type, then hold the card over a torch when turned on in a darkened room.
The light will shine through the plastic and you'll see the wires in between the layers of plastic which spread out from the chip.
Mark where some of these wires run, somewhere away from the chip is prefered so you don't damage the chip.
Then when marked, hold the card over a smooth timber surface, not the nice furniture, but rather a bit of off cut timber, then gently punch a hole through the card with the smallest tip flat blade screw driver you can find.
The broken connection will render the paywave feature in the card useless.
Then run in to bunnings for a test.
Each time I have done this, I have kept the chip and magnetic strip working well with this method, and had the pay rob thingy fail when tested.
A friend at bank X tells me they are looking at releasing cards without it as they get so many folk either doing this or asking for it to be removed.
