A system and method for processing digital payments using a smart chip payment acceptance module associated with an Internet of Things (IoT) or vending device via a virtual EMV terminal process for cloud-based digital payment transactions. A short-range communication channel is provided between a mobile user device and the payment acceptance module. The mobile user device includes a wallet application with an integrated merchant application used to create a payment transaction. An unlock device enables digital secure remote payments (DSRP). A smart chip server connected to a payment gateway can generate an encrypted proof of payment (POP) message indicating completion of the payment transaction. The user can complete the payment transaction using the integrated wallet application within the user device in an online or offline mode of the vend device for seamless interaction with the system by a new user as well as improved flexibility for merchants and consumers.

A method for carrying out a cryptocurrency blockchain transaction through an integrated circuit payment card using a multi-signature blockchain wallet includes: storing, in an integrated circuit of a payment card, a first private key of a first cryptographic key pair and a transaction account number; receiving, by the integrated circuit, a blockchain transaction from a point of sale device, the blockchain transaction including unspent transaction outputs, destination addresses, a cryptocurrency amount for each destination address, and a first digital signature generated using a second private key of a second cryptographic key pair; digitally signing, by the integrated circuit, the blockchain transaction using the first private key to generate a second digital signature; and transmitting, by the integrated circuit, the digitally signed blockchain transaction including the first digital signature and the second digital signature to the point of sale device.

Method and system for use of an EMV card in a multi-signature wallet for cryptocurrency transactions

A method for acceptance of blockchain payment at a traditional point of sale device direct to a merchant includes: receiving an authorization request for a fiat payment transaction including a transaction account number, transaction amount, and merchant identifier; identifying blockchain payment acceptance for a transaction account associated with the transaction account number; transmitting an address request to an exchange server including the merchant identifier; receiving a destination address associated with the merchant identifier for a blockchain network from the exchange server; transmitting a new blockchain transaction to a blockchain node in the blockchain network including the destination address and a cryptocurrency amount based on the transaction amount; and transmitting an authorization response for the fiat payment transaction to a payment network for routing to a point of sale device, the authorization response including an indication that clearance and settlement of the fiat payment transaction is not required.

The present disclosure generally relates to controlling operation of service devices. A payment network server receives, from a merchant aggregator, an operation request from a user for operation of one or more service of the devices associated with the merchant aggregator, the operation request comprising identification data of each service device, an operation mode selected by the user for each service device, and a payment token of the user; identifies, based on the identification data of each service device, a device server communicatively connected with the service device; communicates, to the respective device servers, operation instructions for controlling access to the service devices, the instructions comprising activating the service devices, thereby permitting the user to access the service devices; determining a payment amount for operation of the service devices requested in the operation request based at least on the selected operation modes; and processing a payment transaction for paying the payment amount to the merchant aggregator using the payment token.

Electronic system and computerized method for controlling operation of service devices

The present disclosure generally relates to electronic systems and computerized methods for verification of transacting parties to process transactions. A payment network server receives details of a transaction fulfilled by an agent and generates a transaction identification plaintext. A first party keyset for the first transacting party and an agent keyset for the agent is identified. The server generates cryptograms and ciphertexts encrypted by the first party keyset and agent keyset and sends the cryptograms to the first transacting party and agent. An encrypted cryptogram contains an encrypted ciphertext which contains a plaintext representing the transaction identification plaintext. The ciphertexts are exchanged between the first transacting party and agent by a computer handshake for decryption. The plaintexts are extracted from the ciphertexts and compared against the transaction identification plaintext for verifying the first transacting party and agent.

A system for providing a service at a self-service machine having a device identifier and that does not have internet connectivity or that is in an off-line state includes: a validation server that stores the device identifier, the validation server being in communication with a mobile device of a user, but not with the self-service machine. The self-service machine is configured to: receive a selection of a service; generate a service request identifier for the selected service; add the service request identifier to a list of service requests to be fulfilled; and communicate, to the mobile device by a first direct communication method, service request data including the service request identifier, a terminal identifier of the self-service machine, and an address of a validation server.

An inventory management server is provided. The inventory management server includes at least one processor, and at least one memory. The at least one memory includes computer program code configured to cause the inventory management server at least to receive tracking data assigned to a product from a payment network, interrogate a mapping table containing assigned product to tracking data information, for the presence of the received tracking data, update an inventory database of the product stocked at the merchant inventory in response to detection of the presence of the received tracking data, and transmit acknowledgement data indicative of the inventory database update. The tracking data is transmitted by a merchant via a payment terminal in communication with the payment network.
