Proximity card with incorporated pin code protection
First Claim
1. An electronic identification system for transmitting identification data from a proximity device to a reader, comprising in combination:
- a data source in said proximity device;
a data receiver in said reader;
said proximity device and said reader coupled by proximity antenna means to each other;
means for entering personal identification numbers into said proximity device;
first comparison means within said proximity device to compare said personal identification numbers with first reference identification numbers stored in said proximity device;
means to enable data transmission of additional data from said proximity device to said data receiver on said comparison means showing equality in said personal identification numbers and said stored reference identification numbers; and
means to inhibit data transmission if said comparison means shows inequality of said personal identification numbers and said stored reference identification numbers.

Abstract
An identification card, typically of the proximity type, having on its outer structure a numeric keyboard. When approaching a high security entrance, the user enters into the card a PIN code known only to himself or a few others. The PIN code entry is compared to a reference code within the card and if correct enables the logic system of the card. When the card is next placed in proximity to a Reader antenna, a normal read occurs, that is the data of the card is transferred to the Reader. The card acts as a data source. Identification data is transferred during the read action, and also financial transactions, and an emergency code if the user is under duress and requests emergency help. The data sent to the Reader is also optionally sent to a higher order data processing system such as a central computer. In a second embodiment, the proximity circuits and antenna are made integral to a hand held palm top or lap top computer or cell phone. Thus the computer or cell phone also serves as an identification device. The security system which reads the card is also able to transfer complex data to a central point. The PIN code entry expires after a brief time interval, so that each use of the card requires re-entry of the PIN code.

26. An electronic identification system for allowing access to protected areas, comprising:
-
a portable device provided with a first memory including stored first data information and stored second data information, a first comparison device and an input device for entering said first data information into said portable device;
a reader provided with a second memory including initially stored second data information and a second comparison device, said reader associated with the protected areas;
a communication device for communicating between said portable device and said reader;
wherein said first comparison device compares said first stored data information with the first data information entered by said input device, said communications device transmitting said stored second data information to said reader only if said stored first data information matches the entered first data information, and further wherein said second comparison device compares said stored second data information transmitted to said reader with said initially stored second data information, and further wherein access is allowed to the protected area only if said stored second data information transmitted from said portable device to said reader matches said initially stored second data. - View Dependent Claims (27, 28, 29, 30, 31, 32)
