A method for performing a secure payment in an offline mode in an electronic device is provided. The method includes launching a secure application at the electronic device, obtaining a nonce token from an authentication unit of the electronic device, obtaining a nonce signature from a server via a network, entering an offline mode where the electronic device is disconnected from the network, encrypting, by the secure application, a user credential input by a user using the nonce token and the nonce signature, decrypting and validating, by the authentication unit, an encrypted user credential, generating a secure object based on the decrypted user credential and a random number generated by the authentication unit and performing a secure payment based on the secure object.

The invention relates to an enabling card as well as a system and method for completing a financial transaction in a P.O.S. terminal comprising: a processor carried by the enabling card for: establishing a connection with a mobile device; receiving secure information from a mobile device and generating a digital signal; a coil carried by the enabling card for generating a magnetic field in response to the digital signal to simulate the swipe of card in the P.O.S. terminal and complete the financial transaction.

A system that includes a fuel dispenser terminal and a remote controller. The fuel dispenser terminal is configured to generate a service request for a fuel purchase that includes card information, encrypt the service request, and send the encrypted service request to the remote controller. The fuel dispenser terminal is further configured to receive a personalized offer in response to sending the encrypted service request and display the personalized offer. The remote controller is configured to decrypt the service request to identify the card information associated with a customer and determine an identity of the customer based on the card information. The remote controller is further configured to generate a personalized offer for the customer based on their identity and send the personalized offer to the fuel dispenser terminal. The remote controller is further configured to re-encrypt the service request and send the re-encrypted service request to a service processor.

The invention relates to a method for processing transactional data, implemented within a secured intermediate server, connected to a communications network. Such a method comprises: reception, by the secured intermediate server, of a request for payment comprising a piece of data representing an identification of a communications terminal used by a user to carry out a purchase operation with a merchant server connected to said communications network; setting up a secured point-to-point link with a payment module of the communications terminal; transmission, to said payment module, of a request for execution of payment; reception, by the payment module, of a piece of information on payment; transmission of a message of information to the merchant server.

A portable device receives an account information request signal from a merchant machine. The portable device transmits a response message to the merchant machine. The response message comprises the account information for a purchase. The portable device transmits a first message to an account server. The first message comprises a request to get information comprising the purchase amount. The portable device receives a second message comprising the information from the account server. The portable device sends the purchase amount to a display.

Disclosed herein are methods, devices, and apparatuses, including computer programs stored on computer-readable media, for processing certificates in a blockchain system. One of the methods includes: causing a smart contract to be generated in the blockchain system, wherein the smart contract includes computer-readable instructions for processing certificates; after the smart contract is generated, sending a first request for a first transaction to the blockchain system, the first transaction causing the blockchain system to execute the smart contract to generate a certificate specification based on the first request; receiving, from the blockchain system, the certificate specification; and sending, to the blockchain system, a second request for a plurality of second transactions, the plurality of second transactions causing the blockchain system to execute the smart contract to generate a plurality of certificates.

The method in the embodiments includes: generating, by a server, first transaction information, where the first transaction information is used to indicate that a first participant has obtained control permission, the first transaction information includes information about the first participant and first data that includes information about a second participant, and the control permission is permission to control a target device; sending, by the server, the first transaction information to a blockchain; when the control permission is revoked, generating, by the server, second transaction information, where the second transaction information includes second data, and there is a correspondence between the second data and the first data; and sending, by the server, the second transaction information to the blockchain.

In some implementations, a computing device may obtain an original digital media asset published to a server device along with a distributed ledger that tracks ownership of the original digital media asset. The computing device may generate a customized digital media asset that replaces the original digital media asset, and modify the distributed ledger to indicate the customization or modification of the original digital media asset and identify the customized digital media asset and the ownership thereof. The computing device may publish the customized digital media asset to a server device for distribution. Upon transfer of ownership of the customized digital media asset to a new owner, the distributed ledger may be modified to indicate the new ownership of the customized digital media asset.

Payment platforms such as point of sale terminals can send test transactions to an acquirer processor certification and analytics system for certification of the payment platform's readiness to perform financial transaction processing with payment networks. A payment platform sends a test transaction to an acquirer processor and receives a unique request identifier. The request identifier and a test identifier associated with the test transaction are sent to an analytics engine that retrieves data associated with the test transaction from the acquirer processor, and expected values based on the test identifier. The analytics engine performs a comparison and determines a certification result for the payment platform based on the comparison. Based on certification results, authorization or licenses can be granted to payment platforms to use payment networks of the acquirer processor.

An access device is provided for use in an access control system. The access device includes a processor having control of a door lock, and a communication module connected to the processor. The processor is able to receive a reservation certificate presented by a portable terminal through the communication module. The processor activates the door lock when the current reservation certificate has been presented and disables an alarm system when the current reservation certificate has been presented.
