Embodiments of the invention are directed to an embodiment of a keyboard application in which a plurality of selectable items (representing keys) are associated with transactions. The keyboard application may be imported into any application that utilizes text input, and replaces a default keyboard used to provide the text input. Upon selection of one of the plurality of selectable items, a transaction is initiated by a service provider computer. In some embodiments, the transaction may result in the engagement of a third party entity. Once completed, an access credential associated with the completion of the transaction is generated. The access credential may be entered into the text input field of the application that utilizes text input.

Provided is a security key input system using a one-time keypad. The security key input system may include: a keypad input unit configured to output a security keypad including one or more null keys each having no identification mark written thereon, and receive a security key from a user; a control unit comprising a one-time keypad generator configured to generate a one-time keypad; an input terminal comprising an NFC recognition unit configured to provide the one-time keypad generated by the one-time keypad generator to an output terminal through NFC with the output terminal contacted with the input terminal; a display module; an NFC recognition module configured to receive the one-time keypad from the input terminal through the NFC recognition unit; and the output terminal comprising a controller configured to output the one-time keypad received from the NFC recognition module through the display module.

A method of generating a shared augmented reality payment authentication entry interface includes detecting a first consumer device and a second consumer device; prompting a display of a first augmented reality payment authentication interface at the first consumer device; and prompting a display of a second augmented reality payment authentication interface at the second consumer device.

A system for accepting the input of a PIN comprises a first device receiving a randomized PIN layout derived on a fourth device. The randomized PIN layout is displayed on a display of the first device. A second device comprises an input for accepting a series of key presses to produce a PIN token. The PIN token indicating each of the series of key presses. A third device is in communication with the second device. The third device derives the randomized PIN layout and receives the PIN token from the second device without the PIN token being present on the first device. The third device combines the PIN layout and the PIN token to produce a PIN. The PIN is used to authenticate a transaction. The fourth and third devices each store a shared secret used to independently derive the randomized PIN layout on the fourth and third devices.

This application relates to a financial payment method using biometric information. Biometric information of an individual collected in a mobile device of an affiliated member is transmitted to a mobile device of the individual to allow the biometric information to be authenticated in the mobile device of the individual. After the authentication of the biometric information, a substitute key that corresponds to a card password preset by the individual is inputted, and a financial payment is requested based on the payment content.

In some examples, a wireless card reader detects insertion of a chip card at a chip card reader interface that includes electrical contacts positioned in the wireless card reader to contact contacts of the chip card when inserted into the wireless card reader. The wireless card reader may send, to a mobile computing device, a wireless communication request to send a PIN to the card reader. The card reader may receive, from the mobile computing device, a wireless communication including the PIN entered by a user on the mobile computing device. The card reader may send the PIN for authentication of the PIN. The card reader may receive a confirmation that the PIN has been authenticated. The card reader may send, to the mobile computing device, via the communication component, an indication of the confirmation that the PIN has been authenticated.

An in-vehicle payment system and a method for generating authorization information using the same are provided. The in-vehicle payment system includes an authentication number input device including an interface of a vehicle configured to receive an input from a user, and generate and output input signals corresponding to a manipulation pattern of the interface, a code display device configured to display a code table in an array form including a plurality of code values based on received code information on a screen, and an authorization information generator configured to generate the code information and transmit the code information to the code display device, and recognize an authentication number input by the user using the code information and preset matching information to generate authorization information corresponding to the authentication number when the input signals are received from an authentication number input device.
