  • Patent number: 11501274
    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: 11461760
    Abstract: Systems, apparatuses, and methods for performing transactions through mobile communication devices using either telecommunications networks or proximity near-field communications systems are disclosed. A mobile communication device may display an application authentication element. The application authentication element may include a pre-selected authentication element and transaction data associated with a transaction conducted by a mobile communication device. The mobile communication device may obtain the pre-selected authentication element by either transmitting a request to a server computer or retrieving the pre-selected authentication element from a secure memory in the mobile communication device. A user authentication token may be received by the mobile communication device from the user. The mobile communication device may generate a secret token that is derived from the user authentication token. If the secret token is correlated to a secret reference token, then a transaction may be conducted.

  • Patent number: 11443321
    Abstract: Methods and systems for dynamically generating a verification value for a transaction and for utilizing such value to verify the authenticity of the payment service application. The dynamically created verification value may be generated on a payment device, such as an integrated circuit credit card or smart card, embedded into the payment data, and transmitted to a point of sale terminal. Alternatively, payment data is sent by a payment device to a point of sale terminal, which generates a verification value and embeds it into the payment data. The embedded verification value is used by a service provider to verify the authenticity of the transaction. The methods and systems may be used in a contactless (wireless) environment or a non-wireless environment.
