The device includes a controller, a memory, and a transceiver. The controller generates authentication information based on a user input to the device. The memory stores the generated authentication information. The transceiver receives authentication information, which is generated by a point of sale (POS) terminal based on a user input to the POS terminal, from the POS terminal, when the device enters within a predetermined range from the POS terminal. The controller compares the generated authentication information with the received authentication information, and provides card information which is used in a transaction with respect to an item or a service to the POS terminal based on a result of the comparison. ## Claims ### Claim 1 A device comprising: a controller that is configured to generate at least one authentication information based on a user input to the device; a memory that is configured to store the generated authentication information; and a transceiver that is configured to receive authentication information, which is generated by a point of sale (POS) terminal based on a user input to the POS terminal, from the POS terminal, when the device enters within a predetermined range from the POS terminal, wherein the controller is configured to compare the generated authentication information with the received authentication information, and provide card information which is used in a transaction with respect to an item or a service to the POS terminal based on a result of the comparison. ### Claim 2 (depends on 1) The device of claim 1, wherein the provided card information is transmitted from the POS terminal to a transaction server. ### Claim 3 (depends on 2) The device of claim 2, wherein the card information that is provided to the transaction server is used by the transaction server to perform the transaction with respect to the product or the service. ### Claim 4 (depends on 2) The device of claim 2, wherein the controller is configured to provide coupon information which is used in the transaction with respect to the item or the service to the POS terminal. ### Claim 5 (depends on 1) The device of claim 1, wherein the controller is configured to preset a type of the authentication information according to a payment amount of the item of the service to be purchased based on a user input. ### Claim 6 (depends on 1) The device of claim 1, wherein the generated authentication information includes at least one of an image of a pupil of a user, a voice of the user, a fingerprint of the user, and a signature of the user. ### Claim 7 (depends on 1) The device of claim 1, wherein the controller is configured to generate a plurality pieces of the authentication information, and the comparison comprises comparing one of the plurality pieces of the authentication information with the received authentication information. ### Claim 8 (depends on 7) The device of claim 7, wherein the controller is configured to provide one of the plurality pieces of the authentication information to the POS terminal, and the provided one of the plurality pieces of the authentication information is transmitted from the POS terminal to a transaction server. ### Claim 9 (depends on 8) The device of claim 8, wherein the one of the plurality pieces of the authentication information that is provided to the transaction server is used by the transaction server to perform the transaction with respect to the item or the service. ### Claim 10 (depends on 1) The device of claim 1, wherein the controller is configured to request the transaction to the POS terminal, and the transaction request is authenticated based on the result of the comparison. ### Claim 11 A method of requesting, by a device, a transaction with a point of sale (POS) terminal, the method comprising: generating at least one authentication information based on a user input to the device; storing the generated authentication information; and receiving authentication information, which is generated by the POS terminal based on a user input to the POS terminal, from the POS terminal when the device enters within a predetermined range from the POS terminal, comparing the generated authentication information with the received authentication information, and providing card information which is used in a transaction with respect to an item or a service to the POS terminal, based on a result of the comparing. ### Claim 12 (depends on 11) The method of claim 11, wherein the provided card information is transmitted from the POS terminal to a transaction server. ### Claim 13 (depends on 12) The method of claim 12, wherein the card information that is provided to the transaction server is used by the transaction server to perform the transaction with respect to the product or the service. ### Claim 14 (depends on 12) The method of claim 12, further comprising: providing coupon information which is used in the transaction with respect to the item or the service to the POS terminal. ### Claim 15 (depends on 11) The method of claim 11, further comprising: presetting a type of the authentication information according to a payment amount of the item of the service to be purchased based on a user input. ### Claim 16 (depends on 11) The method of claim 11, wherein the generated authentication information includes at least one of an image of a pupil of a user, a voice of the user, a fingerprint of the user, and a signature of the user. ### Claim 17 (depends on 11) The method of claim 11, wherein the generating comprises generating a plurality pieces of the authentication information, and the comparing comprises comparing one of the plurality pieces of the authentication information with the received authentication information. ### Claim 18 (depends on 17) The method of claim 17, further comprising: providing one of the plurality pieces of the authentication information to the POS terminal, and wherein the provided one of the plurality pieces of the authentication information is transmitted from the POS terminal to a transaction server. ### Claim 19 (depends on 18) The method of claim 18, wherein the one of the authentication information that is provided to the transaction server is used by the transaction server to perform the transaction with respect to the item or the service. ### Claim 20 (depends on 11) The method of claim 11, further comprising: requesting the transaction to the POS terminal, and wherein the transaction request is authenticated based on the result of the comparing.
