New applications can be added to or deleted from an existing smart card without having to issue a new card. To do this, we are committed to working with a variety of products and technologies on a non-exclusive basis. American Express will continue to leverage multiple technologies to deliver smart card products that enhance customer value. American Express is a leader in the multi-application smart card arena. In conjunction with Hilton Hotels Corporation and IBM, the company was the first to introduce a multifunction smart card in the U.S. hotel industry with a smart card pilot at eight participating Hilton hotels.
