Chip cards make our day-to-day transactions more secure. They also make them more frustrating. The Mastercard Biometric Credit Card aims to be even more secure than its predecessors, and much easier to use. By embedding a fingerprint sensor on the end of the card opposite the chip, it lets the terminal authenticate the sale almost instantly, with no need to ever take your hand off the card or for new merchant hardware. The tech is currently testing in South Africa, with tests planned for Europe and Asia in the coming months.
