Abstract: An electronic business card information exchange method and device are provided in the present invention. The electronic business card exchange is achieved by way of by way of receiving by a first terminal in a power-off state an induced electric energy provided by a second terminal, sending by the first terminal the first electronic business card information stored locally to the second terminal under the driving of the induced electric energy, then receiving and storing second electronic business card information written by the second terminal. The technical problem in the prior art that the electronic business card information exchange can not be achieved when one of two terminals is in a power-off state is solved.
