A digital pen ( 1 ) contains an identity tag reader ( 3, 4 ) for identifying places, individuals or items to each of which a written data record relates. Each place or individual is marked with an identity tag ( 20, 36 ) whose identity and location are recorded in a database. The digital pen reads the tag and stores and uploads its identity in association with the penstroke data record, providing a verifiable indication that the data record was created at the tag location. The data record may require to be written within a defined time period after reading the tag. The database may be used to produce forms ( 22, 30 ) on digital paper for use with the pen in creating hospital, maintenance and inspection and other records.
