ELI5: Why we use chip readers.

Chip readers seem a lot slower to work, and the swipe method really doesnt have anything significantly wrong about it.

The magnetic stripes on the back of payment cards are easy to read and easy to program, making them extremely easy to clone. An attacker only needs about 2 seconds with your card to read the data off the mag stripe, which can then be programmed on to a card of theirs and they can make payments with your (cloned) card.

Chip and PIN introduces a few new factors. Not only is it extremely difficult to clone a chip, but you also need a PIN code to authorise the transaction. It makes it a hell of a lot harder for an attacker to fraudulently clone cards, and as long as the majority of banks issue chip cards and the majority of merchants have chip and PIN readers, fraud levels go down. 

EDIT: Never even considered that OP could be in the US, and apparently there is no PIN associated with chip payments in the US. The same thing stands about it being harder to clone though.
