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.
