Computer implemented method, system and apparatus for processing various transactions using a plurality of transaction cards

A transaction system for performing a transaction with plural institutions using plural transaction cards, said transaction system comprising:

• a server;
• a database connected to said server, said database stores attribute information of transactions which can be conducted by transactors with said institutions;
• a plurality of transaction processors for permitting a transactor to perform transactions with said institutions using one or plural transaction cards;
• and
• a network which interconnects said server with said transaction processors,
• wherein each transaction processor receives a first transaction card of a transactor, inputs and then checks identification numbers corresponding to said first transaction card based on attribute information retrieved from said database by said server, displays a screen which includes a plurality of transaction keys based on attribute information retrieved by said server, permits said transactor to select a transaction key of a desired transaction, receives one or more other transaction cards required for said desired transaction, judges whether identification numbers corresponding to said one or more other transaction cards in accordance with said desired transaction are required to be entered based upon attribute information retrieved by said server from said database and executes transaction processing between one or more of said institutions based on attribute information retrieved by said server from said database and the input of identification numbers of said first transaction card or the input of identification numbers of said one or more other transaction cards required to be entered.

A computer program stored on a storage medium for execution in a transaction system to cause said transaction system to perform a transaction with plural institutions using plural transaction cards, said computer program when executed in said transaction system causes said transaction system to perform the steps of:

• receiving a first transaction card of a transactor;
• inputting and then checking identification numbers corresponding to said first transaction card;
• displaying a screen which includes a plurality of transaction keys;
• permitting said transactor to select a transaction key of a desired transaction;
• receiving one or more other transaction cards required for said desired transaction;
• judging whether identification numbers corresponding to said one or more other transaction cards in accordance with said desired transaction selected in said permitting step are required to be entered;
• and
• executing transaction processing between one or more of said institutions based on the input of identification numbers of said first transaction card or the input of identification numbers of said one or more other transaction cards required to be entered.

A transaction processor for use in a transaction system for performing a transaction with plural institutions using plural transaction cards, said transaction system includes a server, a database connected to said server, said database stores attribute information of transactions which can be conducted by transactors with said institutions, a plurality of said transaction processors and a network which interconnects said server with said transaction processors, said transaction processor comprising:

• a display;
• a card reader;
• an input apparatus;
• and
• a controller with controls and display, card reader and input apparatus such that said transaction processor receives a first transaction card of a transactor, inputs and then checks identification numbers corresponding to said first transaction card based on attribute information retrieved from said database by said server, displays a screen which includes a plurality of transaction keys based on attribute information retrieved by said server, permits said transactor to select a transaction key of a desired transaction, receives one or more other transaction cards required for said desired transaction, judges whether identification numbers corresponding to said one or more other transaction cards in accordance with said desired transaction are required to be entered based upon attribute information retrieved by said server from said database and executes transaction processing between one or more of said institutions based on attribute information retrieved by said server from said database and the input of identification numbers of said first transaction card or the input of identification numbers of said one or more other transaction cards required to be entered.
