Open the first and second pages of the passportwhere a photograph. The facing pages are covered with a special transparent film, so that others cannot make changes to the data shown here. On passportsx modern sample film has a holographic pattern.
Rotate the passport 90° so that the picture was at the bottom. In the upper part there are three sets of numbers. The first two groups (two digits) is a series of the passport. The last group (six digits) is the number of the passport.
On other pages of the passport (if flipping it in the same position) the series and number of passport will be indicated below in the form of figures carved out of round holes. To read the number of the passport from the other pages a bit more complicated.
