MasterCard has unveiled a new credit card that incorporates a fingerprint scanner built right into the bottom of the card. In an effort to make payments a more seamless experience and improve security, MasterCard is testing out the new cards in South Africa, with more trials to come in Europe and Asia-Pacific later this year. The cards can be used at existing terminals around the world and would replace the need for signing or putting in a PIN number to authorize a purchase. Warwick Business School associate professor Pinar Ozcan said the announcement is a continuation of a push towards more contactless solutions. Once the card is registered, users will put the card into a card reader or bank terminal and then place a finger on the sensor in the card, which can store two prints. The benefits of having such a card include things like detecting and preventing fraud, increasing approval rates, reducing costs, and increasing customer loyalty.
