Many (most?) do, however, store the photo image and that can be used for recognition via recognition technology.
Coincidentally, I was reading the New Zealand Immigration department is starting a project next quarter to use facial recognition tech and data matching against the passports and issuing authority database for entry purposes. Just use case and road map study at this point, but from what I was reading, likely to go into effect if they can be certain the issuing authority data is secure, accessible in real time, and reliable.
