Smart card capable of independently displaying information

摘要

A smart card capable of independently displaying information is wirelessly connectable to an external interface. The smart card includes a main body, an antenna module, an electronic paper, a drive member and a radio frequency identification chip isolated from the drive member. The antenna module includes a first antenna for receiving first electromagnetic wave and a second antenna for receiving/transmitting second electromagnetic wave. The first and second antennas are respectively connected to the drive member and the radio frequency identification chip. The information can be independently displayed on the smart card to ensure confidence of the data. Moreover, the smart card can be more conveniently used.

主权项

1. A smart card capable of independently displaying information, the smart card being wirelessly connectable to an external interface, the smart card comprising:
a main body; an antenna module disposed on the main body and including a first antenna and a second antenna, the first antenna serving only to receive only a first electromagnetic wave transmitted from the external interface, the second antenna serving to receive/transmit a second electromagnetic wave, and the first electromagnetic wave received by the first antenna having a frequency different from that of the second electromagnetic wave received by the second antenna; an electronic paper disposed on the main body; a drive member disposed in the main body and electrically connected to the electronic paper and the first antenna, according to the received first electromagnetic wave, the drive member controls the electronic paper to display information associated with the first electromagnetic wave directly; a radio frequency identification chip disposed in the main body and electrically connected to the second antenna for receiving/transmitting the second electromagnetic wave, the radio frequency identification chip being isolated from the drive member, wherein the first electromagnetic wave contains a graphic signal and electrical energy, by means of the electrical energy and the graphic signal, the drive member driving the electronic paper to display the information; and wherein electrical energy of the first electromagnetic wave received by the first antenna is used to operate the smart card mechanically.
