Disclosed herein are an authentication and payment system and method. The authentication and payment system of the present invention includes an issuer server, an issuer information management intermediate server, an acquirer server and a payment server. The issuer server issues, manages and operates payment means.

Authentication and payment system and method using mobile communication terminal

Disclosed herein are an authentication and payment system and method. The authentication and payment system of the present invention includes an issuer server, an issuer information management intermediate server, an acquirer server and a payment server. The issuer server issues, manages and operates payment means. The issuer information management intermediate server manages URL information required to access domestic and foreign issuer servers. The acquirer server performs payment approval and performs acquisition and settlement for member stores. The payment server intermediates between the issuer server and the acquirer server to provide an authentication and payment service in response to a request from a terminal of the merchant. Accordingly, the present invention can provide a safe and convenient payment process with respect to payment means, such as credit cards, electronic money or mobile phone micro payment that can be selected between a purchaser and a merchant.

The present invention is directed to a method of payment using a wireless Internet comprising the step of storing individual identification information provided from a user in an authentication server; authenticating the service server when request of the stored individual identification information is received from the service server, and transmitting the stored individual identification information to the service server when the authentication has succeeded; transmitting a message of requesting a service access to a mobile terminal of the user from the service server; and transmitting the individual identification information sent from the authentication server to the mobile terminal by means of a transmitting query of the individual identification information from the mobile terminal.

Authentication for service server in wireless internet and settlement using the same

The present invention is to provide individual and payment information to a service server by recognizing whether the service server is to be trusted when individual identification information provided by a user is received from the service server. So, the invention provides an authentication method of the service server and a payment method by using the same, which can prevent the individual identification information and payment from being accessed by a distrusted server in wireless Internet. This present comprises acts of: storing individual identification information provided from a user in an authentication server; authenticating the service server when request of the stored individual identification information is received from the service server, and transmitting the stored individual identification information to the service server when the authentication has succeeded; transmitting a message of requesting a service access to a mobile terminal of the user from the service server; and transmitting the individual identification information sent from the authentication server to the mobile terminal by means of a transmitting query of the individual identification information from the mobile terminal.

The RFID system includes an RFID reader for sending information selected from among collision type information, idle type information, and readable type information, to all of the RFID tags depending on the number of signals in the corresponding time slot, and RFID tags for performing functions, in which, when information, indicating that a current time slot is a collision type, is fed back from the RFID reader, each of RFID tags selects one arbitrary value of either 0 or 1 and is assigned a time slot, in which a corresponding RFID tag will send a signal to the RFID reader, based on the selected value, a single tag group that caused a collision is divided into two sub-groups depending on the assigned time slots, and tags of the sub-groups send signals, including IDs thereof, to the RFID reader in different time slots for the respective sub-groups.

An antenna for a folder type communications handset. The handset comprises first and second enclosures pivotably joined to permit rotation of one enclosure relative to the other enclosure. The antenna is disposed over a ground plane formed in a printed circuit board in the first enclosure. The second enclosure also comprises a ground plane. A feed terminal and a ground terminal of the antenna are disposed to limit field coupling between the feed terminal and the ground plane in the second enclosure. The feed and the ground terminals are each connected to corresponding terminals on the printed circuit board by meanderline conductors.
