Abstract: 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.
