A further aspect of the invention provides a computer program product recorded on a medium for carrying out a method of distributing smart card information comprising the steps of: acquiring electronic information from a first smart card; acquiring an electronic address from a second smart card; and sending the information from the first smart card to the electronic address of the second card.

Another aspect of the invention provides a means for transferring personal data electronically comprising: identifying the information to be transferred; selecting the application capable of performing this action; sending the data to the destinations specified; and filing it away in a suitable place and format.
In this way a large amount of bulky data is not accumulated daily.
It is only necessary to carry ones own details around and only one copy at that.
Information is less likely to become unruly, since it is stored electronically.
The personal data comprises business card details and is encoded using Smart Card technology.
The application capable of accessing the information contained within is a Java Card Applet, which constructs two standard electronic address messages containing this information and forwards them to the addresses cited.
The notes can then be suitably filed.
A global positioning system that actively guides blind pedestrians and military/police forces.
This system uses DoD Global Positioning System (GPS) to provide user position and navigation to centimeter accuracy.
Present position and navigation requests are digitally cellular telephoned to a central "base station" where data is correlated with a computerized map database which holds names and coordinates of specific locations, such as streets; intersections; traffic lights; hospitals; bathrooms; public telephones; and internal layouts of major buildings and facilities, in selected regions, cities, and neighborhoods.
System operates by user entering desired destination into hand-held unit via voice recognition software or using Braille keyboard.
Hand-held unit then transmits present position (PP) GPS satellite signals and desired destination to a base station which contains map database and surveyor quality GPS computer system.
The present invention relates generally to navigation systems which calculate the position of the user using a GPS link, and more specifically to a GPS navigation system tailored for use by the visually impaired.
Finding one's exact location in an unfamiliar city has presented a problem.
Discovering a location is even more challenging for the visually impaired
The visual clues used by sighted individuals in an unfamiliar place are useless to the blind pedestrian.
To provide the military with a location determination system, the U.S. Department of Defense (DoD) has devised a system that can very accurately locate any point in three-dimensional space.
This system is known as the global positioning system (GPS).
There are twenty-four non-geosynchronous satellites circling the earth as part of a $12 billion DoD location determination system.
An accurate location can be determined by measuring the distance to at least three satellites.
Since the signals produced by the satellites are not classified by the military, civilian companies have produced portable GPS receivers for determining exact locations on the earth.
A GPS receiver can pinpoint a location on the earth to within about 100 meters.
This invention relates to map positioning hardware for continuously establishing a user's geographical position and providing progressive vectors/directions to/within selected destinations or facilities by voice output and/or Braille map displays.
Specifically, this invention is a reduced weight, extremely accurate global positioning active navigation system for both visually handicapped and DoD/police users.
This device phonetically describes user's geographical position and provides phonic and/or braille vectors to/within selected destinations.
It differs from ALL other GPS systems by its incorporation of digital cellular telephone link to a city/regional base station.
The significant advantage is realized by: Marked weight reduction and bulk of the hand-held unit because GPS computations, map database, and voice recognition hardware and files are all relocated from hand-held unit to the base station; and centimeter system accuracy and reduced hardware costs because the entire network (hand-held units and base station) rely upon the base station's single survey-grade GPS system which has proven accuracy of 2-3 centimeters.
With the survey-grade GPS system centrally located, redundancy of having one GPS computer per hand-held unit is eliminated.
The ability to accurately navigate is severely challenged by blindness and/or darkness, especially when the user is not familiar with his/her surroundings/environment.
