Embodiments provide for a method of allowing for communication between a portable device comprising a portable device NFC antenna and a user device comprising a user device NFC antenna using a bridge apparatus comprising a large coil, a small coil, and an amplifier circuit electrically coupling the large coil and the small coil. The method includes the small coil in the bridge apparatus receiving a near field communication (NFC) signal from the user device NFC antenna. The amplifying circuit can amplify the NFC signal to obtain an amplified NFC signal. The large coil in the bridge apparatus can transmit, to the portable device NFC antenna, the amplified NFC signal.

A method performed by at least a user device comprising an interaction application and a biometric application is disclosed. The method comprises receiving from an access device, a message comprising interaction details. The user device may perform a biometric verification of the user operating the user device. The method may then include, if the biometric application has a biometric verification result, the interaction application receives the biometric verification result from the biometric application and continues processing the message. Or if the biometric application does not have the biometric verification result, then the interaction application either waits for the biometric verification result from the biometric application or continues processing the message without the biometric verification result.

A client device may be used to interact with the transaction module of the portable device via a communication element. In some embodiments, the client device may be configured to receive an account identifier from the transaction module, generate and transmit an authorization request message to an authorization entity, and upon receiving authorization from the authorization entity, cause the transaction module on the portable device to update a balance associated with the disbursement module.

Portable device loading mechanism for account access

Provided are methods, systems, and computer program products for verifying a payment device using a magnetometer. The method includes detecting a magnetic signature of a payment device based on a magnetic field of the payment device affecting the magnetometer. The magnetic signature may be determined based on the structural composition of the payment device or a circuit arranged on or embedded in the payment device. The method also includes receiving payment device data for a transaction requested between an account associated with the payment device and an account of a merchant. The method further includes comparing the magnetic signature detected from the payment device with a stored magnetic signature associated with the payment device. The method further includes, in response to determining that the magnetic signatures match, approving the transaction.

Provided is a method for providing installment payment options for a payment transaction. The method may include communicating, to a customer device, installment payment data associated with a plurality of installment payment options. A first authorization request for a payment transaction with a customer may be received from a merchant system. The first authorization request may include at least one field including first installment payment data associated with a first installment payment option. A first lender system associated with the first installment payment option may be determined. A second authorization request, which may include the first installment payment data, may be communicated to the first lender system. An authorization response may be received from the first lender system indicating approval of the first installment payment option for the payment transaction. The authorization response may be communicated to the merchant system. A system and computer program product are also disclosed.

Method, system, and computer program product for providing installment payment options for a payment transaction

Methods and systems are disclosed for enabling transaction processing utilizing a single device. A mobile device can store an application comprising first and second software modules. One module may execute acceptance processing while another software module may emulate a transaction device associated with a user. One or more identifiers (e.g., QR codes, bar codes) may be obtained corresponding to one or more physical items. Authorization may be requested via the mobile device. In response, data may be exchanged between the software modules and this data (e.g., transaction data, a payment token, a cryptogram, etc.) may be provided to a remote computer (e.g., a cloud based acceptance service) that can generate an authorization request message for the transaction.

Mobile application integration

A method is disclosed. The method comprises transmitting, by an access device to a communication device, a resource provider certificate and an access device certificate. Then, establishing a secure channel between the access device and the communication device using data from the resource provider certificate and the access device certificate. Then, transmitting to or receiving data from the communication device using the secure channel.

Efficient authentic communication system and method

The method includes receiving, in an interaction by a switch computer from a second device, data associated with a machine readable code generated by a first application on a first device and provided by a first device to a second application on the second device. The method also includes determining, by the switch computer, a first server computer associated with a first application, transmitting the data associated with the machine readable code and the interaction data to the first server computer, which processes the data associated with the machine readable code and the interaction data, determining, by the switch computer, a second server computer associated with the second application, and transmitting, by the switch computer, a communication to the second server computer. The communication informs the second server computer that the first server computer processed the data associated with the machine readable code and the interaction data.

Two-dimensional code compatibility system

A method is disclosed. The method includes receiving, by a user device from the access device, a routing path list comprising a first set of network nodes. After receiving the routing path list, the user device determines a routing options list comprising a second set of network nodes based on the first set of network nodes in the routing path list. The method also includes obtaining an encrypted credential or token, and transmitting, by the user device to the access device, the routing options list, and the encrypted credential or token to the access device. The access device transmits an authorization request message comprising the encrypted credential or token, and the routing options list to a server computer via at least some of the network nodes in the second set of network nodes. The server computer may be an authorizing entity computer.

Secure and privacy preserving message routing system

Described herein are a system and techniques for conducting transactions upon receiving a biometric sample from a user. In some embodiments, a security device obtains a biometric sample from a user. The security device then provides the biometric sample, or a biometric template derived therefrom, to a service provider, which is able to identify and authenticate the user based on the biometric sample. The service provider then obtains access credential and/or supplemental information for the user and provides it to the security device. The security device is then capable of completing a transaction using the received access credential data. In some embodiments, this may involve generating a cryptogram to be used in the transaction.
