Abstract

A machine readable passport document contains an unbound data page mounted in the document in a secure and tamper-resistant manner. The data page is printed as a separate sheet and contains a photographic image, bearer identification data and machine readable data, all imprinted on a single paper surface. The data page is mounted within the document by means of a heat activatable adhesive and is covered by a transparent sheet. An improved method of assembling a passport document includes the use of a folder having a transparent sheet and a dry adhesive sheet. The data page is placed in the folder which is inserted into a bound passport booklet. The booklet is then heated and compressed to mount the data page in the document. Visa data pages are mounted in the same manner.
