where is the security code on a visa credit card
Card security code The card security code is typically the last three or four digits printed, not embossed like the card number, on the signature strip on the back of the card. On American Express cards, the card security code is the four digits printed (not embossed) on the front towards the right. The card security code is not encoded on the magnetic stripe but is printed flat.
United States Passport Card The passport card is a limited travel document, valid only for land and sea travel within North America (Canada, the United States, Mexico, the Caribbean, and Bermuda). It cannot be used for international air travel. The Department of State indicates that this is because "designing a card format passport for wide use, including by air travelers, would inadvertently undercut the broad based international effort to strengthen civil aviation security and travel document specifications to address the post 9/11 threat environment".[9]
