Abstract
Abstract The present invention pertains to an electronic data access and retrieval system comprising at least first and second smart cards, a first card being encoded with digital data fields representative of predetermined information and a second card including authorization codes for enabling access to and authorized retrieval of selected information from digital data fields of the first card, and includes computer means including display means for displaying the access data. A method is also disclosed of operating an electronic secured access verification display system for displaying an indication of permissible and non-permissible access to a facility of authorized personnel and for verifying the identity of such personnel by providing IDENTITY SMART CARDS, one for each authorized person, and an ACCESS SMART CARD to each authorized operator of the system.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
188 words
An electronic data access and retrieval system comprising: at least first and second smart cards, a first card being encoded with at least on digital data field representative of predetermined information and a second card means including authorization codes for enabling access to and authorized retrieval of selected information from said digital data fields of said first card, said second card means being selected from an integrated circuit containing card of PROM or enabled system; and computer means including display means for displaying the accessed data and having at least first and second smart card read/write means operatively connected to said computer means for reading data fields from and writing data fields to said first and second smart cards; whereby when said first smart card is placed into said first read/write means and said second smart card communicates with second read/write means, access to and authorized retrieval of at least some of the data fields contained in the said first card is enabled and displayed; wherein said second card means additionally contains at least one digital data field which can be accessed by additional separate second card means.
Claim 2
Dependent Claim
188 words
An electronic data access and retrieval system comprising: at least first and second smart cards, a first card being encoded with at least on digital data field representative of predetermined information and a second card means including authorization codes for enabling access to and authorized retrieval of selected information from said digital data fields of said first card, said second card means being selected from an integrated circuit containing card of PROM or enabled system; and computer means including display means for displaying the accessed data and having at least first and second smart card read/write means operatively connected to said computer means for reading data fields from and writing data fields to said first and second smart cards; whereby when said first smart card is placed into said first read/write means and said second smart card communicates with second read/write means, access to and authorized retrieval of at least some of the data fields contained in the said first card is enabled and displayed; wherein said second card means additionally contains at least one digital data field which can be accessed by additional separate second card means.
Claim 3
Independent Claim
128 words
A method of accessing and retrieving digital data information comprising the steps of: a) encoding a first smart card with a multiplicity of digital data fields representative of predetermined information; b) encoding a second smart card means or reader capable system with authorization codes for enabling access to and authorized retrieval of selected data field information from said digital data fields of said first card; c) electronically reading said authorization codes from said second smart card means and retrieving said selected information from at least one of said digital data fields contained in said first smart card; and d) displaying the said selected information; wherein said second smart card means includes at least one digital data field which can be accessed by yet another second smart card means.
Claim 4
Independent Claim
128 words
A method of accessing and retrieving digital data information comprising the steps of: a) encoding a first smart card with a multiplicity of digital data fields representative of predetermined information; b) encoding a second smart card means or reader capable system with authorization codes for enabling access to and authorized retrieval of selected data field information from said digital data fields of said first card; c) electronically reading said authorization codes from said second smart card means and retrieving said selected information from at least one of said digital data fields contained in said first smart card; and d) displaying the said selected information; wherein said second smart card means includes at least one digital data field which can be accessed by yet another second smart card means.
