Disclosed is a method for processing the issuance of a mobile credit card, which is capable of shortening the time taken to issue a mobile credit card and in which card information transmitted from a card company server to a financial chip is processed by a one-time transmission. Thus the frequency of stoppages in the issuance of a credit card, which are caused by disconnections or interferences in a wireless communication, is reduced and stability of issuing a credit card is improved.
