A system for automatically obtaining a printable photographic image of an object for a document, particularly adaptable to police traffic-ticket dispensing situations is described. A tablet computer with a stylus input display device has a video camera device associated with it that points at the object of the document, in the preferred example the object of the document being the suspect or perpetrator of the offense. Wireless communication with a printer affiliated with another computer in the police car makes printing of the ticket easy, and additional wireless connections to remote databases provides the officer at the scene with confirmation of the object's identity and additional information. The end result is a ticket or document that is self proving and can be used to confirm the identity of the holder of the document when presented. This system can also be used in transportation, commercial, and medical settings. Many additional applications for authenticating transactions of various types are described, and electronically transferable documents may be used in place of printed documents in some embodiments.
