| 20110125502 | Method of putting identification codes in a document - A method of putting identification codes in a document is disclosed. The method adds a speech-purpose print code in a document such that an OID pen can emit sound after the OID pen reads the speech-purpose print code. The software program first acquires the position of each word in the document and then automatically puts a speech-purpose print code corresponding to each word in the position of each word so that a user can rapidly generate a document with speech-purpose codes. | 05-26-2011 |
