It's not Square's defence. It's every merchants'/processors' defence.

I have a card with information stored on a magnetic strip, a smart card, RFID and text. It doesn't matter which of these you use to steal the information, the result is the same.

Yeah, but if the costumers are cautious to always use the chip instead of the magnetic strip it's much more difficult for criminals to steal the info without the owner noticing it.
