Definitions

  • the present invention relates generally to the field of electronic information storage and retrieval means and more particularly to an improved system for transferring and keeping information exchanged between business contacts.
  • the predominant current usage of the magnetically encoded business card system of the present invention is as a means for improving the exchange and storage of information such as is normally transmitted in the form of printed business cards.
  • Business cards are a conventional means for transferring information among business people. They serve to refresh the memory of recipients as to the names and other details regarding persons they have met during their business introductions. In addition, business cards frequently convey certain detailed information, such as telephone and telefacsimile ("fax") numbers, which might not be verbally exchanged during a meeting. Furthermore, business cards are often transferred by means other than personal exchange. For example, a salesperson may leave his or her business card when potential customers are not present during a sales call, so that the customers will know who has called and can contact the salesperson if they so desire.
  • the idea of using magnetically encoded information on the business cards themselves has been advanced by U.S. Patent No. 4,774,618, issued to Raviv.
  • the Raviv invention contemplates that a portion of magnetic material may be affixed to business cards such that either the card or the magnetic portion thereof may be attached to a floppy disk type apparatus. The magnetic material may then be written to and/or read from, with the aid of specialized software, using a conventional floppy disk drive and computer combination.
  • Raviv contemplates significant effort on the part of the user in order to obtain the advantages of the invention, and use of the Raviv invention requires considerable time and effort, at least equivalent to that involved in the "keying" of data from conventional business cards into a computer. This is particularly so if one is to utilize the inventive means of placing data onto a business card as well as to later retrieve data therefrom. It would seem that the Raviv invention might be particularly adapted for specialized applications wherein the distribution of the subject business cards is rather limited.
  • the preferred embodiment of the present invention is a business card data storage and retrieval system having a computerized data storage and retrieval unit with a magnetic strip reader.
  • the magnetic strip reader is adapted for reading data from magnetic strips encoded on magnetically encoded business cards.
  • the magnetically encoded business cards are like in size to conventional paper business cards. Also like conventional business cards, the inventive magnetically encoded business cards may be imprinted on both sides, as is customary, for example, on the business cards of those individuals who have international business interests. In such usages, business cards are frequently printed in two different languages, with one language being used on each of the two sides of the card. Unlike conventional business cards, each of the inventive magnetically encoded business cards has thereon a magnetic strip for storing the same data which is printed on the card, as well as additional information as may be desired.
  • the computerized data storage and retrieval unit is similar to some conventional small "notebook” type portable computers, except that it is equipped with the magnetic strip reader and, further, except that it has software adapted for storing, sorting, and retrieving the data stored on the magnetic strips of the magnetically encoded business cards.
  • information may be retrieved in essentially any arrangement and order, and according to essentially any criteria which a user might find useful.
  • the computerized data storage and retrieval unit may, optionally, be provided with means for accomplishing various other computerized functions, such as data communications, calculation, and word processing.
  • An advantage of the present invention is that data may be quickly and easily transferred from business cards into computer memory.
  • a further advantage of the present invention is that information can be conveniently stored and quickly and easily retrieved.
  • Yet another advantage of the present invention is that magnetically encoded business can be inexpensively mass produced.
  • Still another advantage of the present invention is that, in at least some instances, more information can be stored and transferred on a business card than is possible using conventional business cards.
  • Yet another advantage of the present invention is that data obtained from business cards can be sorted and retrieved according to the needs of the user.
  • Still another advantage of the present invention is that standardized formats are employed which facilitate the exchange of business card information.
  • Yet another advantage of the present invention is that data pertaining to a number of individuals can be simultaneously displayed and arranged in a meaningful order, as for example in correspondence to the seating order of those individuals at a business meeting.
  • Still another advantage of the present invention is that a user may enter personal notes pertaining to each business card to be stored and retrieved with the business card information.
  • Yet another advantage of the present invention is that data may be stored, manipulated, and retrieved in more than one language.
