A method for authenticating a consumer. The method includes receiving an authorization request message associated with a consumer conducting a transaction with a portable consumer device. A challenge message is sent to the consumer, where the challenge message is dynamic or semi-dynamic. A challenge response message is received from the consumer, and an authorization response message is sent to the consumer. The authorization response message indicates whether or not the transaction is authorized.

Facilitating transaction status indications for point-of-sale (POS) systems is described. A POS application stored on a POS terminal of a POS system may communicate with a payment reader device coupled to the POS terminal and a payment server application. The POS application may receive, from a customer device associated with a customer and via a short-range communication network, payment information for satisfying a cost of a transaction. The POS application may send the payment information to the payment server application to attempt to authorize the payment information for the cost of the transaction and may receive, from the payment server application, an indication of a status of the transaction. Responsive to receiving the indication of the status of the transaction, the payment reader device and the customer device may output respective aspects of a transaction status indication associated with the status of the transaction.

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 system for determining whether shoppers are eligible for frictionless checkout is disclosed. The system has a processor that obtains image data captured using image sensors positioned in a retail store. The processor analyzes the image data to identify at least one shopper at one or more locations of the retail store. The processor detects, based on the analysis of the image data, at least one product interaction event associated with an action of the at least one shopper at the one or more locations of the retail store. Further, based on the detected at least one product interaction event, the processor determines whether the at least one shopper is eligible for frictionless checkout. In response to a determination that the at least one shopper is ineligible for frictionless checkout, the processor causes delivery of an indicator that the at least one shopper is ineligible for frictionless checkout.

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 method for realizing an EMV contact transaction without a password, wherein said method is implemented by an EMV IC card and a terminal, wherein when a terminal receives transaction information, it sets a password-free function setting; performs an offline data validation and limitation; performs terminal risk management and a behavior analysis; determines, on the basis of the password-free function setting, whether to perform online processing and performs transaction termination processing; the password-free function setting comprises: when an optional kernel configuration flag in an application parameter corresponding to the current application acquired is set and the transaction amount in the transaction information is greater than a password-free IC card transaction limitation amount, the current application is configured so that verifying the cardholder's PIN is obviated. The present invention allows password-free small-amount transactions, and obviates to upgrade IC cards.

Systems and methods are provided for facilitating network transactions. One exemplary method includes receiving, from a terminal, a request for a conversion option for a transaction to a payment account, where the request includes a transaction amount for the transaction in a first currency and an identifier associated with the payment account. The exemplary method also includes determining a charge rate for the payment account for conversion of the transaction amount to a second currency, determining the conversion option for the transaction in the second currency based on at least a conversion rate and the charge rate, and transmitting the conversion option to the terminal in response to the request.

Embodiments provide a method of facilitating a payment transaction with a payment card of a customer. The method includes receiving a payment transaction request initiated at a merchant terminal. The payment transaction request comprising at least a merchant transaction amount associated with a purchase entered at a merchant terminal, a PIN of the payment card provided by the customer via a keypad and a customer transaction amount provided by the customer via the keypad. The method includes facilitating verification of facilitating verification of the PIN with a stored PIN. The method further includes, upon successful verification, determining whether the merchant transaction amount conforms to the customer transaction amount. The method further includes facilitating a payment transaction associated with the payment transaction request if the merchant transaction amount conforms to the customer transaction amount.

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.
