Personal portable terminal for financial transactions
First Claim
1. A substantially wallet-sized personal portable hand held terminal device (XATR) including keyboard means for entering transaction data, memory means for at least temporarily storing transaction data and other selected data logic means for performing arithmetic operations on data stored in said memory means and data entered via said keyboard means, display means for selectively displaying data to the operator of said terminal device (XATR), control means for causing predetermined operations to be performed by said terminal device (XATR), means for receiving at least one data storage and transfer card (DSTC) in said terminal device (XATR), receiving and transmitting means located in said terminal device (XATR) for coupling with complementary data receiving an transmitting means in said data storage and transfer card (DSTC) for transferring data between said terminal device (XATR) and said data storage and transfer card (DSTC), means in said terminal device (XATR) for preventing the transfer of data to or from a said contained data storage and transfer card (DSTC) until actuated by the operator of said terminal device (XATR), fixed means for directly connecting said terminal device (XATR) to external devices, said external devices including receiving and transmitting means for transferring data between said external devices and said data storage and transfer card (DSTC) contained in said terminal device (XATR), whereby said terminal device (XATR) effectively functions as a controllable interface device between said at least one contained data storage and transfer card (DSTC) and said external devices, means responsive to the recognition of said external device as being a second substantially wallet-sized personal portable hand held terminal device (XATR), for concurrently entering data in said data storage and transfer card (DSTC) located in said first terminal device (XATR) and a data storage and transfer card (DSTC) located in said second connected terminal device (XATR), said last named means being responsive to the approval by both operators of said terminal device (XATRs) for entering data in said both data storage and transfer card (DSTCs) after the data is first displayed on said display means which approval is signified by said operators deactivating said means for preventing in said both terminal devices (XATRs).
