The UK uses those too, with the square gold-coloured microprocessor in them. Before that, the same solution was used for BT (British Telecom / Bee Tea) phone cards.
However, what banks claim is untrue: they are not safe!
To maintain compatibility with legacy magnetic strips used by American tourists, all of our microchip bank cards have a magnetic strip on them. Machines check the magnetic strip for a digital flag (0/1, yes/no) to see if a chip present.
Our microchip cards can be easily copied by cloning the magnetic strip, but changing the digital flag when writing the copy
The cloned cards works just like a legacy magnetic strip card, so security has not improved. You can get the software which edits flags online.
