Our machines have been in government installations worldwide for over 60 years. The Ghostwriter T550 has been a popular machine. It offers the ability to sign signatures or short phrases on letters, awards, forms, and other correspondence. You are also able to enlarge or reduce the size of the signature to fit the signing area of the document. As with all Ghostwriter machines, security is a priority. Signatures are not stored in the machine but on a removable device. Machines are also equipped with passcode entry.
