  • Publication number: 20150170120
    Abstract: A method of providing payment services and a messenger server providing the payment services using the method are provided. Also, provided are a messenger application providing payment services and a method of providing the payment services using the messenger application. According to embodiments, when a messenger server receives a request for a payment of goods selected by a user from a seller server, it is determined whether payment information of a user previously registered before the payment is sharable by the seller server. When the payment information is sharable, a signal requesting the payment of the goods is transmitted to a payment server using the payment information of the user, thereby allowing the payment of the goods selected by the user.
