in addition to a regular passport. These ID cards are WHTI and Real ID compliant, making them valid for domestic air travel, and have digitally-signed biometrics within an internal RFID chip, readable at a land or sea port of entry into or out of the United States. Layout Format On the front cover, a representation of the Great Seal of the United States is at the center. "PASSPORT" (in all capital letters) appears above the representation of the Great Seal, and "United States of America" appears below (in Garamond italic on non-biometric passports, and Minion italic on post-biometric passports). An official passport has "OFFICIAL" (in all capital letters) above "PASSPORT". The capital letters of "OFFICIAL" are somewhat smaller than the capital letters of "PASSPORT". A diplomatic passport has "DIPLOMATIC" (in all capital letters) above "PASSPORT". The capital letters of "DIPLOMATIC" are somewhat smaller than the capital letters of "PASSPORT". A Travel Document, in both forms (Refugee Travel Document and Permit to Re-Enter), features the seal of the Department of Homeland Security instead of the Great Seal of the United States. Above the seal the words "TRAVEL DOCUMENT" appears in all capital letters. Below the seal is the legend "Issued by U.S. Citizenship and Immigration Services" in upper and lower case. In 2007, the passport was redesigned after a previous redesign in 1993. There are 13 quotes in the 28-page version of the passport and patriotic-themed images on the background of the pages. A biometric passport has the e-passport symbol at the bottom. There are 32 pages in a biometric passport. Frequent travelers may request 52-page passports for no additional cost. Extra visa pages could previously be added to a passport, but, as of January 1, 2016, the service was discontinued entirely for security reasons. Data page and signature page Each passport has a data page and a signature page. A data page is a page containing information about the passport holder. It is the only page in a U.S. passport laminated in plastic to prevent tampering. A data page has a visual zone and a machine-readable zone. The visual zone has a digitized photograph of the passport holder, data about the passport, and data about the passport holder: Photograph Type [of document, which is "P" for "passport"] Code [of the issuing country, which is "USA" for "United States of America"] Passport Number Surname Given Name Nationality (United States of America)
