In order to overcome the problem of security of paper documents, an electronic token of the type including onboard processing and memory is affixed to the document, and in use the document is placed so that the token couples with an external read/write terminal. Secure information may be accessed from or added to the token only by an authorised person having the correct passwords. The token may also be provided on passports, cheque books, or passbooks. |
