Title:
CONTACTLESS CARD AND COMMUNICATION AND POWER SUPPLY METHOD THEREOF
Document Type and Number:
WIPO Patent Application WO/2016/095801
Kind Code:
A1
Abstract:
Disclosed in the present invention are a contactless card and communication and power supply method thereof, overcoming the inconvenience caused by the slow transmission speed, high cost, and large size of current high-capacity contactless cards. The card comprises: a coupling antenna, used for receiving an external modulation signal and/or carrier signal over a first frequency, which is the centre oscillation frequency; a conversion circuit, used for outputting a direct current voltage on the basis of the modulation signal and/or carrier signal; and a wireless communication module, used for accessing the direct current voltage, and configured to communicate wirelessly on a carrier wave higher than the first frequency; wherein the first frequency is in a preset frequency range. The present invention overcomes the deficiency of the relatively slow transmission speed of contactless cards, and effectively uses the capacity of a contactless card such that the contactless card can simultaneously store abundant information and rapidly transmit information.
