CARD-SHAPED ELECTRONIC DEVICE, COMMUNICATION TERMINAL AND AUTHENTICATION METHOD
First Claim
1. A card-shaped electronic device, comprising:
- an external connection terminal configured to be connected to a card connection terminal of a host having an image pickup unit;
a communication unit configured to transmit and receive data wirelessly to and from another communication terminal;
an image recognition unit configured to extract a characteristic from a recognition image; and
a control unit configured to permit subsequent transmission and reception of data to and from the other communication terminal when a characteristic of a first recognition image photographed by the image pickup unit and a characteristic of a second recognition image transmitted from the other communication terminal correspond to each other.
