Thought PayPal was done upping its mobile payment game when it unveiled its triangular Square competitor earlier this year? Think again. Despite Here being, well, here, PayPal's not satisfied having but one way to scan your plastic, and so it's snapped up Card.io. In case you've forgotten, Card.io gathers credit card info visually using a smartphone's camera -- no scanning dongle required -- to save fingers and thumbs from having to enter payment info manually. Oh, and for folks fearing that PayPal would pull the plug on other apps' access to Card.io's SDK, not to worry -- PayPal assures us that Card.io's technology will remain available to developers.
