A plurality of transactions initiated by a user through a user account and need to be concurrently executed is received. A Nonce list corresponding to the user account and maintained in a blockchain is accessed. The Nonce list includes a plurality of Nonce records, and each Nonce record includes a group identifier and a Nonce value. Available Nonce records are obtained for the plurality of transactions from the Nonce list. The available Nonce records are respectively added to the plurality of transactions. The plurality of transactions are published in the blockchain, so that a node device in the blockchain matches the available Nonce record in a transaction published by the client device with the Nonce records in the Nonce list. When the available Nonce record matches a target Nonce record in the Nonce list, the node device processes the transaction, and concurrently executes a plurality of the processed transactions.

An offline retail machine comprising a short-range transceiver, one or more processors, and memory performs communications operations via one or more mobile devices. The communications operations include establishing via the short-range transceiver a connection with a first mobile device, and transmitting first information to the first mobile device. Upon not receiving an acknowledgement that the first information was received by a remote server, the offline retail machine maintains the first information in the memory and establishes, via the short-range transceiver, a connection with a second mobile device, appends the first information to second information, and transmits the first and second information to the second mobile device. Upon receiving acknowledgement that the first and second information were received by a remote server, the offline retail machine deletes the first and second information.

Computer-implemented services provide personal security monitoring and/or oversight of interactions between parties that may be initiated online, and in some circumstances extended to real-world in-person interactions. Profiles associated with individuals involved in a transaction may be developed and centrally managed. Profiles may contain, e.g., information concerning a user's identity, historical and/or current location information, user communication information, and the like. Profile information may be used by a central security oversight platform and/or provided to third party systems for, e.g., assessing risks involved in a particular interaction, providing accountability amongst users, and assisting law enforcement or third parties in transaction intercession and/or investigation in the event that an interaction results in negative consequences.

A system for communicating with eye wear. The system may include smart glass pairing instructions that are configured to establish a radio frequency (“RF”) communication link between a terminal and the eye wear. The system may include image proximity instructions that are configured to estimate a distance from the eye wear to the terminal. The system may include overlay instructions that are configured to overlay an eye wear display on a view of the terminal through the eye wear. The system may include response instructions configured to receive from a user a response to the eye wear display. The system may include synchronization instructions configured to: define a virtual integrated UI that corresponds to the terminal and the eye wear display; and record a state of the virtual integrated UI.

A computer-implemented system and method for performing social network secure transactions is provided. A message with a hashtag associated with a recipient of payment and payment information including at least a payment source for a payment from a payor to a recipient is received. The message is intercepted from the social network platform for transfer to a separate payment platform. The payment information of the payor is validated and the recipient associated with the hashtag is identified using the list of recipients. The payment information is processed on behalf of the recipient associated with the hashtag using the payment source in the message from the payor.

A mobile device with a first transceiver, a second transceiver, one or more processors, and memory bridges communications between an offline retail machine with a short-range communication capability and a remote server by obtaining via the first transceiver a single-use request code from an information packet broadcast by the offline retail machine; transmitting via the second transceiver the single-use request code to a remote server; obtaining via the second transceiver from the remote server a grant token including the single-use request code; detecting a trigger condition for initiating provision of a product or service by the offline retail machine; and in response to detecting the trigger condition, initiating performance of the provision of the product or service by transmitting the grant token to the offline retail machine via the first transceiver.

Methods for updating an application programming interface (API) field of a transaction message may include receiving, with at least one processor, a payment transaction message, wherein the payment transaction message comprises data associated with a payment transaction; determining, with at least one processor, one or more API fields of the payment transaction message based on the data associated with the payment transaction; and modifying, with at least one processor, one or more API fields of the payment transaction message. Methods may also include transmitting, with at least one processor, a modified payment transaction message based on modifying the one or more API fields of the payment transaction message. Systems and computer program products are also disclosed.

In one embodiment, techniques include systems and methods for facilitating context-aware peer-to-peer transfers of items utilizing at least one of short-range wireless technologies embodied by user devices or device-accessible contact lists. After receiving a request to transfer an item, a server can cause a device of a first peer user to detect devices of second peer users in the proximity of the device of the first peer user using short-range wireless technology. Based at least in part on the detected nearby devices or a contact list of the first peer user stored by the device of the first peer user, a second peer user to receive the item is determined. Upon receiving confirmation of authorization to transfer the item, requested and provided via an electronic message between the respective devices and the server, the item is disassociated from the first peer user and associated with the second peer user.

In one aspect, a method includes receiving, from a sender device, a request to initiate a transfer of an asset to a recipient; causing a user interface to be presented on the sender device to receive an input of an amount of the asset to be transferred; causing an indication of the transfer of the asset to be presented via the user interface in association with a graphical icon representing a gift wrapping that conceals at least some information regarding a payload associated with the transfer; associating the graphical icon with the payload to generate a gift-wrapped element that includes the amount and the information regarding the payload; causing a notification to be sent to a recipient device of the recipient that includes the gift wrapped element; and causing assets in the amount to be withdrawn from an account of the sender and transferred to an account of the recipient.

An information processing method includes: receiving, by a communication part of a terminal, first information relating to a remittance request from a first user, displaying, in a display of the terminal, a first indication based on the first information, displaying, in the display, a second indication that is based on the remittance request and differs from the first indication, receiving, by the communication part, an input by a user of the terminal based on the second indication displayed in the display, and executing, by a processor of the terminal, remittance processing that is based on the remittance request and relates to remittance from the user of the terminal to the first user, based on the input by the user of the terminal.
