Abstract
Abstract An IC card reader/writer apparatus includes at least two contactors in which IC cards are inserted, respectively, card detecting means for detecting that at least two IC cards have been loaded, and collating means for verifying that correct cipher codes of the two IC cards coincide with those inputted externally, respectively, wherein access to the contents stored in the IC cards is allowed only when the collation results in coincidence.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
163 words
An IC card reader apparatus in which information stored in IC cards placed in said apparatus is allowed to be read out by inputting cipher codes specific to said IC cards, comprising: at least two card inserting ports for receiving IC cards, respectively; means for detecting the insertion of said IC cards in said ports; means for determining whether said insertion detecting means has detected the presence of said IC cards at least at said two inserting ports; collating means for verifying whether cipher codes allocated to said two IC cards placed in said inserting ports coincide with the inputted cipher codes, respectively; and means for permitting information to be read out from said IC cards only when said determining means has confirmed the presence of said IC cards at least at said two inserting ports and when the cipher codes of said two IC cards whose presence at said two inserting ports has been confirmed coincide with said inputted cipher codes, respectively.
Claim 2
Dependent Claim
163 words
An IC card reader apparatus in which information stored in IC cards placed in said apparatus is allowed to be read out by inputting cipher codes specific to said IC cards, comprising: at least two card inserting ports for receiving IC cards, respectively; means for detecting the insertion of said IC cards in said ports; means for determining whether said insertion detecting means has detected the presence of said IC cards at least at said two inserting ports; collating means for verifying whether cipher codes allocated to said two IC cards placed in said inserting ports coincide with the inputted cipher codes, respectively; and means for permitting information to be read out from said IC cards only when said determining means has confirmed the presence of said IC cards at least at said two inserting ports and when the cipher codes of said two IC cards whose presence at said two inserting ports has been confirmed coincide with said inputted cipher codes, respectively.
Claim 3
Dependent Claim
187 words
An IC card reader and writer apparatus in which information stored in IC cards placed in said apparatus is allowed to be read out or information is allowed to be stored in said IC cards placed in said apparatus by inputting cipher codes specific to said IC cards, respectively, comprising: at least two card inserting ports for receiving said IC cards, respectively; means for detecting the insertion of said IC cards in said ports; means for determining whether said insertion detecting means has detected the presence of said IC cards at least at said two inserting ports; collating means for verifying whether the cipher codes allocated to said two IC cards placed in said inserting ports coincide with said inputted cipher codes, respectively; and means for permitting information to be read out from or written in said IC cards only when said determining means has confirmed the presence of said IC cards at least at said two inserting ports, respectively, and when the cipher codes of said two IC cards whose presence at said two inserting ports has been confirmed coincide with said inputted cipher codes, respectively.
Claim 4
Dependent Claim
187 words
An IC card reader and writer apparatus in which information stored in IC cards placed in said apparatus is allowed to be read out or information is allowed to be stored in said IC cards placed in said apparatus by inputting cipher codes specific to said IC cards, respectively, comprising: at least two card inserting ports for receiving said IC cards, respectively; means for detecting the insertion of said IC cards in said ports; means for determining whether said insertion detecting means has detected the presence of said IC cards at least at said two inserting ports; collating means for verifying whether the cipher codes allocated to said two IC cards placed in said inserting ports coincide with said inputted cipher codes, respectively; and means for permitting information to be read out from or written in said IC cards only when said determining means has confirmed the presence of said IC cards at least at said two inserting ports, respectively, and when the cipher codes of said two IC cards whose presence at said two inserting ports has been confirmed coincide with said inputted cipher codes, respectively.
