Disclosed are methods for exchanging transaction data, including transmitting a first public encryption key and transaction data associated with a transaction to a computing device via a near field communication (NFC) connection, receiving a second public encryption key and a transaction message associated with the transaction via the NFC connection, and appending the second public encryption key and the transaction message associated with the transaction to a database stored in a memory in communication with at least one integrated circuit, wherein the at least one integrated circuit is powered by an electromagnetic field generated by the computing device. Systems and computer program products are also provided.

Disclosed herein are system, method, and computer program product embodiments for mobile payment handover for self-service terminals. An embodiment operates by generating handover data configured to instruct a user device to settle an amount due. The embodiment further operates by obtaining an electronic confirmation that the amount due has been settled. Subsequently, the embodiment operates by determining that the amount due has been settled responsive to the electronic confirmation.

A client device comprises a first secure element and a second secure element. The first secure element comprises a first computer-readable medium having a payment application comprising instructions for causing the client device to initiate a financial transaction. The second secure element comprises a second computer-readable medium having a security key, a payment instrument, stored authentication data and instructions for generating a secure payment information message responsive to the payment application. The secure payment information message comprises the payment instrument and is encrypted in accordance with the security key.

A system for cashless payment of goods or services is provided which includes at least one payment unit disposed in at least one automat or machine, having at least one transmitting/receiving unit for short range communication; a processing unit; and a memory, wherein the automat or machine is connected to one or more other automats or machines via a short range communication means, at least one mobile device also having a transmitting/receiving device for both short range communication and long range communication, a processing unit and a memory. Many other detailed configurations, functionalities, systems, processes and alternatives thereto are also disclosed.

Techniques for related to retail transaction are disclosed. The techniques involve various uses of a mobile device, such as a cell phone, in authorizing payment for a retail transaction and/or receiving and/or transmitting data to/from the mobile device.

A face recognition-based method includes, when a terminal detects a placement posture on the terminal, obtaining placement posture information of the terminal, where the placement posture information is used to determine a tilt angle of the terminal relative to a first plane; performing facial recognition on a user when determining that a tilt angle meets a preset range without notifying the user and regardless of detecting an action of the terminal other than obtaining the placement posture information; and opening the application when the facial recognition succeeds.

The CLOUD-BASED VIRTUAL WALLET NFC APPARATUSES, METHODS AND SYSTEMS (“EAE”) transform user enhanced security transaction initiation requests using EAE components into time-limited, session-specific transaction bounding tokens. In some implementations, the disclosure provides a processor-implemented method of transforming a transaction bounding token request into transaction bounded tokens and purchase authorizations.

Systems and methods for implementing payments or mobile payments. In an aspect of in-store purchase, a merchant sends a payment amount and merchant account info to transaction center. A buyer sends a code and buyer account info to transaction center. The code represents the merchant. In an aspect of online purchase, an e-commerce merchant provides options for a buyer to use names other than a first name plus a surname. In one embodiment, a buyer submits a shortened name or nickname for online purchases when a given payment service is used as a payment method.

A method for handoff of a transaction for completion includes: registering a payment instrument with a server and storing a payment token that represents the payment instrument; storing a device identifier that corresponds to the payment token in the database record; via a point-of-sale terminal, reading the payment instrument, and transmitting it to the server; via the server, using the payment token to access the device identifier and transmitting a push notification to a device corresponding to the device identifier; upon acceptance of the push notification, executing an application on the device and simultaneously displaying details for the transaction on both the device and the point-of-sale terminal; receiving transaction completion data that is entered via the device and transmitting the transaction completion data to the server; and completing the transaction at the server and notifying the point-of-sale terminal and the device that the transaction is complete.

A system includes a processor and a non-transitory computer readable medium coupled to the processor. The non-transitory computer readable medium includes code, that when executed by the processor, causes the processor to receive input from a user of a user device to generate an optimal payment location on an application display, generate a first boundary of the optimal payment location on the application display of the user device based upon a first motion of a payment enabled card in a first direction and generate a second boundary of the optimal payment location on the application display of the user device based upon a second motion of the payment enabled card in a second direction. The first boundary and the second boundary combine to form defining edges of the optimal payment location.
