A method for optimizing transaction authorization conversion rates using measured feedback includes retrieving payment transaction parameters and authorization results for a plurality of past payment transactions from a database, generating a transaction success model comprising authorization success factors for each of a plurality of payment transaction parameters using data science methods for statistical inference based on the retrieved payment transaction parameters and authorization results, receiving, at an acquirer processor, a payment transaction from a merchant, modifying one or more parameters of the payment transaction according to the generated transaction success model, and submitting the modified payment transaction to a financial institution for processing.

A system, method, and apparatus of authenticating and authorizing a payment are provided. A method includes receiving authentication information gathered by a point-of-sale device from a customer initiating a payment for a transaction via the point-of-sale device; receiving context information gathered by the point-of-sale device; authenticating the customer using the received authentication information; selecting a customer payment profile from a plurality of customer payment profiles to use for the transaction, based on the received context information, wherein each customer payment profile is associated with a payment account; authorizing the payment for the transaction from the payment account associated with the selected customer payment profile; and sending, to the point-of-sale device, a notification that the customer has been authenticated and that the payment for the transaction has been authorized.

Methods for operating a portable electronic device to conduct a mobile payment transaction at a merchant terminal are provided. The electronic device may verify that the current user of the device is indeed the authorized owner by requiring the current user to enter a passcode. If the user is able to provide the correct passcode, the device is only partly ready to conduct a mobile payment. In order for the user to fully activate the payment function, the user may have to supply a predetermined payment activation input such as a double button press that notifies the device that the user intends to perform a financial transaction in the immediate future. The device may subsequently activate a payment applet for a predetermined period of time during which the user may hold the device within a field of the merchant terminal to complete a near field communications based mobile payment transaction.

This invention relates to a method to compensate by a server a clock deviation of a card i by maintaining a time base Tbase (i) synchronized with card i, the method comprising the steps of: receiving at a time TS a dynamic card verification dCVV code value generated by card i; providing a set of at least two dCVV code corresponding to two successive dCVV time periods; if the dCVV code received from card i corresponds to one of the dCVV codes of the provided set but is different from the reference dCVV code, determine the minimum possible timing drift Min_td between the time base maintained by the server for the card and the time base Tbase(i) of the card; updating time base Tbase(i) by addition of a time drift correction equal to the minimum possible time drift Min_td.

The present disclosure generally relates to the use of loyalty accounts, private label payment accounts, and general payment accounts using a wearable electronic device with an electronic wallet. Various accounts are linked to the electronic device. In some examples, the electronic device is NFC-enabled. The electronic device may be used to provide loyalty account information and payment account information to a payment terminal, such as an NFC-enabled payment terminal.

A security code input may be obfuscated from a thermal imaging device by randomly heating a random set of inputs of an input device. The security code is inputted on an input device, which communicates with a security system to grant or deny access to a user based on an entry of the security code. The input device includes a plurality of hearing elements. The input device may receive an input from the user. A random set of heating elements including one or more heating elements, are generated from the plurality of heating elements. A temperature is determined for the one or more heating elements of the random set of heating elements. The temperature is then applied to the one or more heating elements of the random set of heating elements of the input device.

A communication device may receive input from a user and initiate generation of an interaction token in response. This interaction token can be used by the communication device in order search for a specific resource provider computer from among one or more resource provider computers, and to initiate a resource transfer between the user and a specific resource provider, mediated by a token provider computer.

The present invention relates to a method for making available a security key, wherein a smart card adapted according to the invention is employed for the production thereof. In this case, an expedient method sequence is proposed which makes it possible for the smart card to make available, for example, a so-called one-time password or a dynamic check number in interaction with a token server. The present invention further relates to a correspondingly adapted computing arrangement and to a computer program product with control commands which implement the method and/or operate the computing arrangement.

A system (and corresponding method) for facilitating an online transaction initiated by a client at an online address, the system comprising a payment token having a unique identification factor, an authorisation gateway and a data processing unit, the authorisation gateway being adapted to receive the online address and to transmit it to the data processing unit, and the data processing unit being adapted to receive the online address and the unique identification factor and to allow or deny the said transaction or require a further confirmation step based on the online address, the unique identification factor and a set of rules.

Disclosed herein is a computer implemented method for providing authentication for secure transactions in a multi-server system, the method comprising; receiving, at an authentication server from a requestor server, a request for a cryptogram, the request being associated with a transaction and including a requestor identifier; in response to receiving the request, generating a cryptogram; sending, from the authentication server, the cryptogram to the requestor server; receiving, at the authentication server from a merchant server, the cryptogram, a payment token, and a unique merchant identifier, and a merchant secret; validating, at the authentication server, the cryptogram; comparing, at the authentication server, the unique merchant identifier and the merchant secret with a unique merchant identifier and a merchant secret pair stored in a database; and authorizing, at the authentication server, the transaction when there is a match.
