1. A multi-card comprising:
a secure element adapted to allow multiple pieces of card information issued to a same card service to match each of a plurality of fingerprints to store matching results therein; and
a fingerprint sensor configured to receive the plurality of fingerprints inputted thereto, wherein the secure element is configured to:
produce one or more lists for each card service based on an application identifier (AID);
when there are the multiple pieces of card information having a same AID in each list, match the multiple pieces of card information with each of the plurality of fingerprints to generate an internal AID in which information on the plurality of fingerprints is further included in the multiple pieces of card information; and
select a piece of card information corresponding to a fingerprint information input from the fingerprint sensor based on the internal AID to produce transaction response information,
wherein the internal AID is generated by adding arbitrary characters to the AID or applying internal AIDs made by partially changing the AID in the card information having the same AID contained in the respective lists,
wherein the security element is further configured to:
upon a receipt of a selected card service from a payment terminal, retrieve the AID corresponding to the selected card service;
when there are multiple internal AIDs corresponding to the selected card service, select card information that matches the fingerprint information;
when there is only one internal AID corresponding to the selected card service, select card information that matches the AID retrieved, regardless of the internal AID, and
wherein the matching results are set or changeable by allowing the card information to match the fingerprints through a service application driven by a user terminal.
