METHOD FOR CONTROLLING PAYMENT DEVICE FOR SELECTING PAYMENT MEANS

摘要

The present invention proposes a method for automatically selecting a payment method using a payment device, in which the payment device and a payment processing terminal automatically determine a mutual payment method so as to thereby conveniently change a mobile payment environment when the payment device and the payment processing terminal approach (or contact) each other, and in which card information with improved security is acquired from a card company server and provided to the payment processing terminal so as to thereby enable mobile transactions with improved security while using existing payment processing networks. To this end, the method of the present invention is performed by a payment processing application installed in the payment device having a display apparatus so as to be driven, and may comprise the steps of: acquiring payment method information, which is supported by the payment device, from an electronic tag when approaching the electronic tag having payment method information recorded thereon; driving a sub-application of a shared payment method matched from the payment method information and the payment method supported by the payment device; and displaying the interface of the sub-application on the display apparatus.
