A touchless transaction method in which a user executes a transaction without operating an automatic transaction apparatus and which is executed by a transaction management apparatus communicably connected to a mobile terminal and the automatic transaction apparatus used by the user, the touchless transaction method comprising executing, by the transaction management apparatus: an authentication step of authenticating that the user using the mobile terminal is a registered user on a basis of information received from the mobile terminal; a transaction content management step of receiving a prescribed transaction content requested by the user from the mobile terminal and managing the received prescribed transaction content; and an instruction step of outputting to the prescribed automatic transaction apparatus an instruction to execute the prescribed transaction content when identification information for identifying the prescribed automatic transaction apparatus to be used by the user is received, wherein the touchless transaction method is characterized by further comprising: a position confirmation step of confirming that the mobile terminal exists within a prescribed range from the prescribed automatic transaction apparatus between the transaction content management step and the instruction step, wherein the position confirmation step comprises: the mobile terminal executing short-distance wireless communication with the automatic transaction apparatus to confirm whether the mobile terminal and the automatic transaction apparatus exist within a prescribed distance; and the automatic transaction apparatus shooting the user with a camera included in an input interface of the automatic transaction apparatus to confirm that the user carrying the mobile terminal exists in front of the automatic transaction apparatus, and wherein the instruction step is executed when the mobile terminal has been confirmed to exist within the prescribed range in the position confirmation step. an authentication step of authenticating that the user using the mobile terminal is a registered user on a basis of information received from the mobile terminal; a transaction content management step of receiving a prescribed transaction content requested by the user from the mobile terminal and managing the received prescribed transaction content; and an instruction step of outputting to the prescribed automatic transaction apparatus an instruction to execute the prescribed transaction content when identification information for identifying the prescribed automatic transaction apparatus to be used by the user is received, wherein the touchless transaction method is characterized by further comprising: a position confirmation step of confirming that the mobile terminal exists within a prescribed range from the prescribed automatic transaction apparatus between the transaction content management step and the instruction step, wherein the position confirmation step comprises: the mobile terminal executing short-distance wireless communication with the automatic transaction apparatus to confirm whether the mobile terminal and the automatic transaction apparatus exist within a prescribed distance; and the automatic transaction apparatus shooting the user with a camera included in an input interface of the automatic transaction apparatus to confirm that the user carrying the mobile terminal exists in front of the automatic transaction apparatus, and wherein the instruction step is executed when the mobile terminal has been confirmed to exist within the prescribed range in the position confirmation step. a position confirmation step of confirming that the mobile terminal exists within a prescribed range from the prescribed automatic transaction apparatus between the transaction content management step and the instruction step, wherein the position confirmation step comprises: the mobile terminal executing short-distance wireless communication with the automatic transaction apparatus to confirm whether the mobile terminal and the automatic transaction apparatus exist within a prescribed distance; and the automatic transaction apparatus shooting the user with a camera included in an input interface of the automatic transaction apparatus to confirm that the user carrying the mobile terminal exists in front of the automatic transaction apparatus, and wherein the instruction step is executed when the mobile terminal has been confirmed to exist within the prescribed range in the position confirmation step. the mobile terminal executing short-distance wireless communication with the automatic transaction apparatus to confirm whether the mobile terminal and the automatic transaction apparatus exist within a prescribed distance; and the automatic transaction apparatus shooting the user with a camera included in an input interface of the automatic transaction apparatus to confirm that the user carrying the mobile terminal exists in front of the automatic transaction apparatus, and wherein the instruction step is executed when the mobile terminal has been confirmed to exist within the prescribed range in the position confirmation step.
