There's a good reason you don't usually see Square readers outside of the US: they're built to read payment cards with magnetic stripes, not the more secure chip-and-PIN cards that are common everywhere else. All that's set to change, however. Square has revealed plans for a reader that accepts the chip-based EMV format alongside stripes, letting shops handle credit and debit cards from around the world (and the US, once it catches up). The company will only start taking pre-orders for the payment device later this year, but it could be worthwhile for stores and customers alike. Besides the greater availability, it's much harder to clone a chip card -- you shouldn't have to worry about an unscrupulous clerk (or a clever hacker) stealing your credit card and going on a shopping spree.
