Abstract
A method for point-of-sale transactions is disclosed. The method comprises a point-of-sale terminal receiving a confidential information from a portable electronic device over a contactless communication link, the confidential information being used by the point-of-sale terminal to complete the transaction. The method also includes substantially blocking access to the contactless communication link beyond the area adjacent to the point-of-sale terminal to reduce eavesdropping on the confidential information.
