  • Patent number: 10223694
    Abstract: Embodiments of the present invention are directed to systems and methods for providing a central entity that can provision mobile payment applications on mobile communication devices and personalize the mobile payment applications with consumer and account information. The personalization of the mobile payment application on the mobile communication device may include provisioning a payment account on the mobile payment application. The central entity may provision the account on the mobile payment application without interacting with the issuer during the provisioning of the account. The central entity may provision the account on the mobile communication device by decrypting, using a secure element key, encrypted payment account information received from the mobile communication device. The payment account information may be encrypted by a secure element of the mobile communication device using the same secure element key.

  • Publication number: 20190043036
    Abstract: Systems, apparatus, and methods for managing an application installed on a mobile device, such as a mobile phone are provided, so as to prevent or limit unauthorized use of the application, for example, when the mobile device is lost, stolen, or otherwise subject to unauthorized use. A request to enable or disable user access to a function of the application can be received by a server computer. A command message responsive to the request can be generated by the server computer, the command message comprising control data for enabling or disabling user access to the function of the application. The generated command message can be transmitted to the mobile device over a wireless network.

  • Patent number: 10185952
    Abstract: A method is disclosed. The method includes performing a contact transmission of data between a contact interface on a portable device and a first POS (point of sale) terminal with a contact chip reader in a contact payment transaction. The method also includes receiving a command from a payment processing network via an authorization response message through the contact interface on the portable device while the portable device is in contact with the first POS terminal, and then enabling a contactless interface of the portable device based on the command.

  • Publication number: 20190019176
    Abstract: A system, apparatus, and method for processing payment transactions that are conducted using a mobile device that includes a contactless element, such as an integrated circuit chip. The invention enables the updating, correction or synchronization of transaction data maintained by an Issuer with that stored on the device. This is accomplished by using a wireless (cellular) network as a data communication channel for data provided by an Issuer to the mobile device, and is particularly advantageous in circumstances in which the contactless element is not presently capable of communication with a device reader or point of sale terminal that uses a near field communications mechanism. Data transferred between the mobile device and Issuer may be encrypted and decrypted to provide additional security and protect the data from being accessed by other users or applications.

  • Patent number: 10115100
    Abstract: Systems, apparatus, and methods for managing an application installed on a mobile device, such as a mobile phone are provided, so as to prevent or limit unauthorized use of the application, for example, when the mobile device is lost, stolen, or otherwise subject to unauthorized use. An input indicative of a password to access the application can be received. It may be determined that a predetermined number of password entry attempts has been reached based on the input. A request message to disable access to the application can be transmitted from the mobile device to a remote computer. One or more lock instructions for disabling access to the application can be received by the mobile device from the remote computer. The one or more lock instructions can be executed by the mobile device by modifying control data within a secure memory of the mobile device.

  • Publication number: 20180232722
    Abstract: Techniques for enhancing the security of a communication device when conducting a transaction using the communication device may include receiving a cryptogram generation key replenishment request that includes transaction log information derived from transaction data stored in a transaction log on a communication device, verifying that the transaction log information in the replenishment request is consistent with the previously received transaction information, and providing a new cryptogram generation key to the communication device in response to verifying the transaction log information in the replenishment request.

  • Patent number: 9972005
    Abstract: Techniques for enhancing the security of a communication device when conducting a transaction using the communication device may include using a limited-use key (LUK) to generate a transaction cryptogram, and sending a token instead of a real account identifier and the transaction cryptogram to an access device to conduct the transaction. The LUK may be associated with a set of one or more limited-use thresholds that limits usage of the LUK, and the transaction can be authorized based on at least whether usage of the LUK has exceeded the set of one or more limited-use thresholds.

  • Publication number: 20180068296
    Abstract: An interface and device architecture for a payment device. An interface between a payment application installed in a payment device and one or more value-add applications (such as loyalty programs, transit applications, etc.) that are also installed in the payment device. The API or interface design permits communications and data transfer between the payment application and one or more value-add applications. This reduces (and in some cases may prevent) the need for back-end server processing of data that may be relevant to both a payment transaction and to a function of the value-add application. Similarly, the same or another API or interface may enable communications and data transfer between a value-add application and the payment application.

  • Publication number: 20170364913
    Abstract: A system, apparatus, and method for processing payment transactions that are conducted using a mobile payment device that includes a contactless element, such as an integrated circuit chip. The invention enables one or more of the operations of activation of a payment application, transfer of transaction data, updating of account records, setting or re-setting of a payment application counter or register, or transfer or processing of a script, command, or instruction, with these functions being performed with minimal impact on a consumer. This is accomplished by introducing a pre-tap and/or two-tap operation prior to, or as part of, the transaction flow.
