A method for dynamic adaptation of card reader protocol includes: providing a point-of sale (POS) terminal, that accepts login credentials via a magnetic stripe card, displays menu items for selection, adds selected menu items to an order, and accepts payment for the order, where the payment may be obtained via swipe, dip, or tap; via a card reader, reading provided cards when enabled; via a reader controller, determining one or more workflow states of the POS terminal, and controlling states and modes of the card reader; determining a type and capabilities of the card reader upon power up; and receiving instructions indicating the type and the capabilities, and communicating with the card reader according to the type and the capabilities responsive to a common set of commands employed by the POS terminal, and formatting data received from the card reader into a common data format.

In some examples, a mobile card reader includes a card interface to read information from a card, an interface to enable the mobile card reader to communicate with a mobile device, and a processor configured to send security related information of the mobile card reader to an application executing on the mobile device. The security related information may be for transmission by the mobile device to a remote server system. The mobile card reader may receive, from the application, an indication that the application has been validated by the remote server system based on validation of the security related information of the mobile card reader and security related information of the application. In response, the mobile card reader generates a secure session key with which to carry out encrypted communication between the application and the mobile card reader.

The present disclosure relates to a mobile card payment system and method, and more particularly, to a mobile card payment system and method for performing a card payment between mobile communication terminals on the basis of a phone-to-phone payment concept wherein the mobile card payment system is capable of performing a card payment by storing at least one of actual card information and virtual card information regarding normal financial cards including an actual financial card, which has a plastic solid body, and a digital financial card, in which actual card information is stored in a digital type and used, in a card-terminal-specific mobile communication terminal, setting a payment-terminal-specific mobile communication terminal as a card payment terminal, and reading the card information stored in the card-terminal-specific mobile communication terminal.

A method and a system for providing a financial transaction using an empty card are provided. The method for providing a financial transaction using an empty card includes receiving, by a server, a virtual card number generated by a program included in a user terminal, searching, by the server, for an empty card storage location at which the empty card is registered, in a storage location search algorithm based on the virtual card number, searching, by the server, for a real card number storage space linked to a user identification (UID) assigned to the found empty card storage location, extracting, by the server, a real card number stored in the real card number storage space, and performing, by the server, a financial transaction progress or a financial transaction progress request with the extracted real card number.

Embodiments of systems and methods for generating virtual account-linked cards are described. A virtual account-linked card may be generated in response to a determination that a physical account-linked card has been forgotten at a card reader and ingested by the card reader. A virtual account-linked card may be restricted such that it can only be used to execute a transaction with authorized transaction partners identified in a database.

Various embodiments are generally directed to autofilling card data from a contactless card to a form of a computing device. An application may determine that a payment field of a form has received focus. The application may then receive encrypted data from a communications interface of a contactless card associated with an account. The application may then receive, from a server, verification of the encrypted data. The application may then receive, from the server, an encrypted account number associated with the account, and decrypt the encrypted account number to yield the account number. An autofill service of an operating system (OS) executing on the processor circuit, may then autofill the account number to the payment field of the form.

Application management services for simulated contactless cards support applying payment when a provisioned card (cardholder profile) is stored in volatile memory of a computing device by maintaining a first channel open between a payment application and a provisioning service while communicating payment information to a point of sale terminal over a second channel.

Methods and systems are provided for receiving from a remote computing device an indication of a unique identifier that is associated with a digital presentation, which can include a digital representation of value; referencing a datastore to identify the digital presentation; and causing the digital presentation to be presented via the remote computing device, including presenting the digital representation of value consistent with a set of presentation instructions.

A greeting card is provided that includes, for example, two fold lines that define a first panel, a second panel, and a third panel, where each of those panels include front and back surfaces. The second panel includes a void. The back surface of the first panel includes an actionable unique identifier such that when the greeting card is folded along the fold lines the actionable unique identifier is visible through the void. The actionable unique identifier is usable to retrieve a digital presentation.

Disclosed herein is a method and system to establish a secure communication channel between a payment object reader and a payment terminal For this, the server determines whether a payment terminal has associated with an attestation ticket. The method further includes determining, whether to approve or deny the request for establishing the secure communication channel between the payment object reader and the payment terminal based on the attestation ticket. If the determination yields that the request has been approved, further generating a session approval interrupt having one or more session approval conditions; and sending the session approval interrupt to the payment terminal, where the session approval interrupt causes a secure communication channel to be established between the payment object reader and the payment terminal.
