Abstract
Abstract The invention is directed to providing an improved security system for stations issuing IC cards. In accordance with the improved system, two independent codes transmitted from remote locations must match codes retained at the issuing station and on the IC card prior to the system allowing the issuing station to be activated. In particular, a manufacturer's identification code is entered into the IC card prior to the cards leaving the control of the manufacturer. The card issuer provides a secured area wherein a issuer's identification code is maintained. Upon issuance of an IC card, both the manufacturer's and issuer's codes must be transmitted to the station and verified by the corresponding codes maintained at the station and onboard the memory of the IC card before the station will allow an account number to be written into the memory of the IC card. Preferably, the system includes a transmission path from the station to the location where the manufacturer's codes are maintained. Upon the issuance of an IC card, the manufacturer is informed of the card's issuance so that an accurate record may be maintained for all of the cards delivered to an issuer.

Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
194 words
A system at an issuing station for issuing IC cards in which the card manufacturer records a manufacturing code in the card and separately transmits the manufacturing code to an issuing station from a secured source, said system comprising in combination: manufacturer authorization checking means responsive to the manufacturing code recorded in said card and including means for receiving the manufacturing code from the manufacturer, said manufacturer authorization checking means including means for comparing the received and recorded manufacturing codes, and means for producing an authorized card signal when a match is detected between said received and recorded manufacturing codes, thereby identifying the presence of an authorized card; issuer validity checking means for receiving an issuer identification code from a secured control room and comparing the received issuer identification code with an issuer identification code stored in a memory at the issuing station, said issuer validity checking means producing an issuer authorized signal when a match is detected between said received and stored issuer identification codes; and means responsive to the presence of both said authorized card and issuer authorized signals for enabling said issuing station to record information in and issue said card.
Claim 2
Independent Claim
194 words
A system at an issuing station for issuing IC cards in which the card manufacturer records a manufacturing code in the card and separately transmits the manufacturing code to an issuing station from a secured source, said system comprising in combination: manufacturer authorization checking means responsive to the manufacturing code recorded in said card and including means for receiving the manufacturing code from the manufacturer, said manufacturer authorization checking means including means for comparing the received and recorded manufacturing codes, and means for producing an authorized card signal when a match is detected between said received and recorded manufacturing codes, thereby identifying the presence of an authorized card; issuer validity checking means for receiving an issuer identification code from a secured control room and comparing the received issuer identification code with an issuer identification code stored in a memory at the issuing station, said issuer validity checking means producing an issuer authorized signal when a match is detected between said received and stored issuer identification codes; and means responsive to the presence of both said authorized card and issuer authorized signals for enabling said issuing station to record information in and issue said card.
Claim 3
Dependent Claim
27 words
A system as set forth in claim 1 including a decoder onboard said card for receiving said manufacturing code in a ciphered form from said card manufacturer.
Claim 4
Dependent Claim
23 words
A system as set forth in claim 1 including means for notifying said card manufacturer upon the successful completion of issuing said card.
Claim 5
Dependent Claim
17 words
A system as set forth in claim 1 wherein said comparing means is located onboard said card.
Claim 6
Dependent Claim
37 words
A system as set forth in claim 1 wherein said card manufacturer and said secured control room are remotely located from said issuing station and connected to said issuing station by first and second transmission paths, respectively.
Claim 7
Dependent Claim
29 words
A system as set forth in claim 5 wherein said first transmission path is completed by a transmitter at said card manufacturer and a receiver at said issuing station.
Claim 8
Dependent Claim
52 words
A system as set forth in claim 6 wherein said issuing station includes a keyboard and said means responsive to the presence of both said authorized card and issuer authorized signals include means for enabling said keyboard only in response to the presence of both said authorized card and issuer authorized signals.
Claim 9
Independent Claim
132 words
A method for securing an IC card issuing station containing a manufacturer's identification code in a memory onboard said IC cards, said method comprising the steps of: receiving at said issuing station an issuer's identification code from a first secured source and comparing said code with issuer's identification code stored in memory at said issuing station so as to provide a first enabling signal when said issuer's identification codes are complementary. receiving said manufacturer's code from a second secured source and comparing it with said manufacturer's identification code onboard said IC card so as to provide a second enabling signal when said received and onboard manufacturer's codes complement one another; and responding to the presence of both first and second enabling signals by enabling said issuing station to issue said IC card.
Claim 10
Independent Claim
132 words
A method for securing an IC card issuing station containing a manufacturer's identification code in a memory onboard said IC cards, said method comprising the steps of: receiving at said issuing station an issuer's identification code from a first secured source and comparing said code with issuer's identification code stored in memory at said issuing station so as to provide a first enabling signal when said issuer's identification codes are complementary. receiving said manufacturer's code from a second secured source and comparing it with said manufacturer's identification code onboard said IC card so as to provide a second enabling signal when said received and onboard manufacturer's codes complement one another; and responding to the presence of both first and second enabling signals by enabling said issuing station to issue said IC card.
