Described herein are a system and techniques for updating balance information for a disbursement module on a portable device using a transaction module on that same portable device. In some embodiments, each of the transaction module and the disbursement module may be associated with a different transaction processing system. 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

An issuing authority (IA) may validate the identity of a user and issue a digital license to the user. IA may generate IA public-private key pair, and provide IA public key to the certification authority (CA). IA may sign the digital license with IA private key, and provision the signed digital license on the user device. IA may request CA to certify the digital license. CA may use IA public key to validate the digital license, and sign IA public key with CA private key, thereby generating a digital certificate associated with the issuing authority that is linked to the digital license. A relying party may use CA public key to validate the digital license. The relying party can retrieve the information from the digital license and trust that the retrieved information is legitimate.

Method and system for authentication credential

Methods and systems for facilitating a transaction are provided. A transaction involving an integrated circuit user device in contact with an access device is processed in less time, such that the user device can be removed at an earlier time. In embodiments, an access device provides an estimated value to a user device such that a cryptogram can be generated without waiting for a final value. Additionally, the access device can store user device data and then complete the transaction with the user device before authorizing the transaction, such that the user device can be removed without waiting for an authorization response.

System and method employing reduced time device processing

Systems and methods provide dynamic application selection based on contextual data of a transaction. A portable device may include multiple applications with which a transaction may be processed. These applications may be associated with a variety of priorities. The portable device may provide a list of these applications to an access device from which one application may be selected.

Dynamic application selection based on contextual data

Embodiments of the invention relate to systems and methods for provisioning and using a multi-purpose device. The device contains information regarding a plurality of memberships. The device contains one or more membership certificate chains, comprising multiple certificates, wherein a membership provider certificate is signed by a private key associated with a membership root certificate authority, and wherein a member certificate is signed by a private key associated with the membership provider certificate. The member certificate includes member attributes regarding the user, such as member benefit information. The device also includes a payment certificate chain, comprising multiple certificates, wherein a payment provider certificate is signed by a private key associated with a payment root certificate authority, and wherein a payment certificate is signed by a private key associated with the payment provider certificate. The payment certificate includes payment attributes regarding the user, such as a payment account.

Multi-purpose device having multiple certificates including member certificate

A smart device is provided between a transaction terminal (e.g. an access device, a point of sale terminal) and a payment card to facilitate a secure transaction. The smart device receives transaction details from the transaction terminal. The transaction terminal suspends the transaction. The smart device is brought in communication with a payment device in control of the user (e.g. the user of the payment device does not hand over the payment device to a merchant, clerk, waitstaff). The smart device receives a cryptogram identifying an account from the payment device and transmits the cryptogram to the transaction terminal. The transaction terminal resumes the transaction, generates a transaction authorization request message including the cryptogram, and transmits the transaction authorization request message to an issuer of the account. The transaction terminal receives an authorization response message from the issuer, and notifies the smart device of the transaction being approved or declined.

Smart device system and method of use

Techniques are disclosed which include receiving, by a central entity computer, a request for digital currency. The request includes a serial number and a denomination of a physical currency. The central entity computer generates the digital currency for the denomination and linked to the serial number. The generating includes recording the digital currency on a blockchain. The central entity computer transmits a notification of the generation of the digital currency. The central entity computer causes removal of the physical currency from circulation in a fiat currency system.

Digital fiat currency

Systems and methods are disclosed to provide dynamic application selection based on contextual data of a transaction. A portable device may include multiple applications with which a transaction may be processed. These applications may be associated with a variety of priorities. The portable device may provide a list of these applications to an access device from which one application may be selected.

Systems and method for producing, validating, and registering authentic verification tokens are disclosed. Such systems and methods include generating verification token specific key pairs. The key pairs can be signed by a verification token manufacturer master key or public key certificate for an additional level of authenticity. Related methods and systems for authenticating and registering authorized verification token manufacturers are also disclosed. Once a verification token manufacturer is authenticated, it can be assigned a manufacturer-specific key pair or certificate and in some cases, a predetermined set of serial numbers to assign to the verification tokens it produces. Each serial number can be used to generate a verification token specific key pair specific to the associated verification token. One component of the verification token key pair can be stored to the verification token. Optionally, the component of the verification token key pair stored to the verification token can be signed by the manufacturer specific master key or certificate and stored a verification token public certificate.
