 The card's background consists of interweaving smooth curves rich in variable color and microprint.All of the personal information on the card is created by laser engraving, with some key information produced in raised tactile engraving, including the date of birth, vertical letters "USA", the passport card number, and an alphanumeric sequence underneath the photograph.A second, smaller "ghost" photograph of the bearer is included on the right side of the card; when closely inspected this ghost image is actually an approximation of the shading in the original photo composed of various letters from the card holder's name.
