SMART CARD DEVICE, DEVICE FOR GENERATING VIRTUAL CODE FOR AUTHENTICATION, METHOD OF GENERATING VIRTUAL CODE FOR AUTHENTICATION USING THE SAME, AND SERVER FOR VERIFYING VIRTUAL CODE FOR AUTHENTICATION

A method performed by a device for generating a virtual code for authentication, comprising:transmitting (S110), time data to a card upon tagging of the card in which an IC chip has been embedded;receiving (S120), from the card, a first virtual code generated based on the time data;generating (S130)...

Zusammenfassung:A method performed by a device for generating a virtual code for authentication, comprising:transmitting (S110), time data to a card upon tagging of the card in which an IC chip has been embedded;receiving (S120), from the card, a first virtual code generated based on the time data;generating (S130), a second virtual code for authentication by using the first virtual code;transmitting (S 140), the second virtual code to a server; andrequesting (S 150), the server to perform verification on the second virtual code;characterized in that:the first virtual code is generated based on the time data and a first OTP, andthe second virtual code is generated based on the first virtual code, the time data and a first UID, which is identification information of the card.
