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.

Electronic system and computerized method for verification of transacting parties to process transactions

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.

A system and method of conducting an authentication transaction; and a near field communication (NFC) enabled mobile device for conducting the authentication transaction. The method includes the steps of: storing data associated with one or more authentication certificates in a secure element of the NFC enabled mobile device; sending the data associated with the one or more authentication certificates from the NFC enabled mobile device to a server via a NFC enabled transceiver; verifying the authenticity of the one or more authentication certificates at the server; and upon successful authentication, sending transaction data from the server to the NFC enabled mobile device via the NFC enabled transceiver.

System and method of conducting an authentication transaction

A method for conducting a transaction between a merchant and a customer, a merchant device, and a computer storage medium for instructing a computing device to execute a method for conducting a transaction between a merchant and a customer are disclosed. The method includes establishing a secure wireless connection between a merchant device and a customer device, real-time synchronizing, via the secure connection, a shopping cart of the customer between the merchant and the customer devices, determining, via the secure connection, at least one payment option for checking out the shopping cart, and processing, at a transaction processing device, the payment based on a selected payment option out of the at least one payment option.

Method for conducting a transaction

There is provided a data processor implemented method for dynamic authentication of an object. There is also provided non-transitory computer readable storage mediums and systems for carrying out dynamic authentication of an object.

Method for dynamic authentication of an object

System and method for facilitating user identification of a product. The system includes: a receiver unit configured to receive a signal; a memory module in communication with the receiver unit, the memory module having stored thereon product data that is stored in association with a transmittable product identity, wherein the receiver unit is further configured to (i) convert the received signal into its corresponding transmittable product identity and (ii) retrieve the product data from the memory module based on a comparison between the stored transmittable product identity and the converted transmittable product identity; and an output unit configured to output the retrieved product data to a user for facilitating user identification of the product.

Method, medium, and system for facilitating user identification of a product

According to one embodiment of the present disclosure, there is provided a method for receiving an electronic receipt of an electronic payment transaction into a mobile device, the method comprising: storing, into an installed application in the mobile device used to perform the electronic payment transaction, a unique transaction identity issued on the electronic payment transaction; generating, in a server, an electronic receipt issued on the electronic payment transaction; verifying that the electronic receipt matches against the unique transaction identity stored in the installed application; and receiving the electronic receipt into the mobile device in response to the verifying step determining that the electronic receipt matches against the unique transaction identity stored in the installed application.
