A method for querying information in a visual smart card, comprising: a micro control unit receiving, by means of an input device, a query request inputted by a user (S1); the micro control unit determining information queried by a user request according to a received query request (S2); if first information, the micro control unit reading a first information record which is stored thereby, and parsing the first information record to obtain the first information, the first information being displayed by means of a display device (S3); if second information, the micro control unit sending an application selection instruction to a smart card chip, receiving an application selection response returned by the smart card chip, then sending an information record reading instruction to the smart card chip, receiving a second information record returned by the smart card chip, and parsing the second information record to obtain the second information, the second information being displayed by means of the display device (S4). A visual smart card applicable to said method overcomes the shortcomings in the existing technology wherein the assistance of other devices is required, while carrying out querying by means of operating a smart card directly facilitates a holder of a smart card understanding information in the smart card, improving the ease of use of smart cards.

Typically, online transactions, such as online purchases of products or services require entering sensitive transaction information into a third-party web browser or application. This may expose sensitive transaction information to an increased risk of inadvertent disclosure. Apparatus and methods are provided for a smart card which enables users to securely complete online transactions without entering any sensitive transaction information into a third-party system. Vendor websites may be configured to generate a unique code identifying the vendor offering the product/service, the product/service and price of the product/service. The smart card includes a keypad for entering the unique code and completing payment for the desired product/service. The smart card will include a microprocessor and wireless interface. The wireless interface provides wireless communication capabilities and the ability to initiate online payments based on information captured by the keypad.

Typically, online payments require entering sensitive transaction information into a third-party web browser or application. This may expose sensitive transaction information to an increased risk of inadvertent disclosure. Apparatus and methods are provided for a smart card which enables users to securely complete online payments without entering any sensitive transaction information into a third-party system. The smart card may include a touch-sensitive screen configured to display selectable payment options. The smart card may include a microprocessor and wireless interface. The wireless interface may provide wireless communication capabilities and the ability to initiate online payments based on information captured by the touch-sensitive screen.

A card is provided with a light sensor operable to receive information via light emitted from a display screen or another source of light. Accordingly, a mobile telephonic device or portable computer (e.g., tablet computer) may communicate information to a card via light pulses. Information communicated via light may include, for example, points balances, credit balances, debit balances, transaction history, software updates, coupons, promotions, advertisements or any other type of information.

Example embodiments of systems, methods, and computer-accessible mediums for transaction authorization are provided. An exemplary system can comprise a card including an input device and a display device in data communication with a server. The server can generate an authorization passcode upon an initiation of a transaction session, and the card can receive an entered passcode through the input device, display the entered passcode on the display device, and transmit the entered passcode to the server for comparison to the authorization passcode. Upon a determination that the entered passcode is a match for the authorization passcode, the server can transmit a match notification indicating the transaction session is valid, and upon a determination that the entered passcode is a mismatch for the authorization passcode, the server can transmit a mismatch notification terminating the transaction session.

A dual interface smart card having a smart card body, a contact-based interface for contact-based communications, a first security chip which is arranged in the smart card body and is electrically conductively coupled to the contact-based interface, a fingerprint sensor arranged in the smart card body, a second security chip, which is coupled to the fingerprint sensor and is configured to carry out a fingerprint verification by means of fingerprint signals detected by the fingerprint sensor, and an antenna coupled to the second security chip.

The present disclosure provides a card shaped mobile payment device, which includes a card shaped casing and an offline payment execution module configured for executing an offline payment operation and disposed in the card shaped casing. The offline payment execution module includes a display module, a security chip, an antenna unit and a central control unit. The display module is used for displaying card information; the security chip is used for generating a token information, which is time-sensitive, and executing a transaction procedure. The antenna unit is electrically connected to the security chip for providing the token information to a transaction device. The central control unit activates the security chip according to a received identity authentication result, and provides a card index information corresponding to the card information to the security chip, so as to access a stored card credential and generate the token information.

A mobile payment device includes a central control unit, an identity authentication module, an input interface, a display module, a security chip, an induction antenna and a cuboid casing. The central control unit is electrically connected to the identity authentication module, the input interface, the display module, and the security chip. The central control unit selects, according to an input signal inputted by a holder of the mobile payment device, one of at least one card information displayed on the display module to allow the selected card information to serve as payment card information and starts the security chip according to a signal inputted by the holder before making payment, thereby allowing the security chip to provide the payment card information to the induction antenna.

Various embodiments are generally directed to techniques to perform transaction with transaction cards utilizing characteristics of customer's signature. Techniques may further include determining characteristics of a signature including a reduced set of data points for the signature and storing the characteristics in secure memory of transaction card. The transaction card including the characteristics are used to perform transactions, such as those performed at Point-of-Sale (POS) terminals.
