An opt-in email system in which a recipient that has opted in to an email list can recognize and trust that an email has actually come from a desired sender. When a recipient desires to opt-in to an e-mail list, the recipient is sent to a trusted third party certification service that generates a certificate associated with a key pair. A key is maintained at the sender's location by a secure cryptographic device that can verify the certificate and create a signature, using a key of the key pair, for messages intended for the recipient. When a message intended for the recipient is received from the sender, the signature will be verified based on the status of the certificate and the corresponding key of the key pair. If the signature does not verify, it indicates that the recipient has not opted-in to receive emails from this sender.

The present application describes systems and methods for creating a document having metadata using a pointing device such as a digital pen. In one configuration, a digital pen captures pen stroke data and processes that data to determine metadata that the pen then writes to metadata storage located on the document.

A printing system is provided that dynamically adjusts the method of printing an image based on the lightness or darkness of the medium upon which the image will be printed. The reflectivity of the medium upon which an image is to be printed is determined, and the way in which the image will be printed is adjusted based on the determined reflectivity of the medium. For lighter colored mediums, on which sufficient contrast will be provided, the image can be printed directly onto the medium. For darker colored mediums, on which the ink used to print the image will not provide enough contrast with respect to the medium to produce a reliably readable image, the method of printing the image is modified to ensure that sufficient contrast is always provided to produce a reliably readable image.

The present application describes systems and methods for composing documents using a digital pointing instrument. In further configurations, a user utilizes a pen to partially fill in a form and provide destination data whereby a forms processor adds additionally required information to the form in order to compose a complete form that is sent to the destination.

The present application describes systems and methods for identifying the version of a form using a digital pointing device. In one example, a form includes an RFID tap or barcode including a form version number. When a user is prepared to fill in the form, the digital pen checks a form database to determine if the form version is acceptable. If the form version is not acceptable, the digital pen indicates to the user that the form is not acceptable using an indicator.

This invention is a system that enables handicapped and disabled individuals to control and use office photocopiers. The foregoing is accomplished by coupling a interface to a diagnostic communication port on the photocopier. The diagnostic port may be used to simulate the pressing of keys on the photocopier control panel. A software program running on a personal computer is coupled to the interface so that the interface may duplicate the actions of the photocopier control panel. A voice, keyboard and touch screen interface is added to the software program to permit several keys to be issued with a single phrase or touch. The user may use voice or the keyboard or the touch screen or any combination of the above to operate the photocopier. The addition of wireless audio may also be utilized to allow hands-free operation of the photocopier. An audio voice feedback provides information about what command was exactly executed. The system audibly reports the status of the photocopier.

Methods and systems for dispensing value are described. In one configuration, a unique tangible indicia is enabled with a value and then disabled after the value is redeemed. In another configuration, a user enables a unique coded stamp and associates a postage payment with the stamp. The postal service cancels the stamp by deactivating the stamp from a list of active stamps and optionally audits the payment association.
