Secure credit card with near field communications
First Claim
1. Apparatus comprising, in combination:
- a near field communication device for transmitting information by inductive electromagnetic coupling over a range of ten centimeters at a radio frequency and having automatic peer-to-peer network setup without requiring establishment of device configuration when engaged and selectively operable in an active or passive mode, said near field communication device including storage means for storing information to be returned upon interrogation thereof;
means for generating identification information for storage in said storage means or transmission by said near field communication device upon activation of said apparatus,andmeans for nulling a portion of said storage means containing said identification information upon expiration of a selected period of time subsequent to said activation of said apparatus.

Abstract
A near field communication device included in a secure transaction card provides an addition and/or transitional communication link for communicating secure transaction information. The near field communication device may be selectively engaged or disengaged and, when engaged, either active or passive modes of operation of the near field communication device can be selected. in the active mode, secure transaction information is transmitted upon establishment of a communication link with a complementary near field communication device. In the passive mode, secure transaction information is transmitted upon interrogation from a complementary near field communication device. Secure transaction information is generated and stored for transmission in a memory and at least a portion of the memory is erased or nulled upon transmission or upon expiration of a selected period of time.

2. A method of communicating secure transaction information, said method comprising steps of
engaging a near field communication device for transmitting information by inductive electromagnetic coupling over a range of ten centimeters at a radio frequency and automatic peer-to-peer network setup without requiring establishment of device configuration and selectively operable in an active or passive mode in a secure transaction card, upon engagement of said near field communication device, generating secure transaction information, storing said secure transaction information in a memory of said near field communication device for transmission by said near field communication device, and nulling a portion of said memory upon transmission of said secure transaction information or upon expiration of a selected period of time subsequent to said engagement of said near field communication device.
