The present document describes a payment method for a fleet, an electronic device and a storage medium. The method includes: sending payment request information of a fleet to a roadside payment terminal, such that the roadside payment terminal sends the payment request information of the fleet to a payment server; receiving, from the roadside payment terminal, fleet payment information generated by the payment server; and performing a payment operation according to the fleet payment information. Accordingly, the traveling efficiency of the fleet can be improved.

This disclosure describes, in part, techniques for enabling merchant devices to interoperate with one another in a more robust manner, such that overall operation and efficiency within a merchant establishment is improved. For instance, the techniques described herein may enable the intelligent routing of requests between devices within the merchant establishment based on real-time locations of the devices, which devices are associated with which orders, and the like.

Methods and systems of providing verification of the identity of a digital entity are provided, including receiving information and a public key of the digital entity, wherein the information has been previously attested to in an attestation transaction stored within a centralized or distributed ledger at an attestation address, the centralized or distributed ledger providing a record of transactions; deriving an attestation address using the information and the public key of the digital entity; verifying the existence of the attestation transaction at the attestation address in the centralized or distributed ledger and verifying that the attestation transaction has not been revoked; receiving at the processor associated with the user a cryptographic challenge nonce signed by the digital entity's private key; and verifying the digital entity's identity with the cryptographic challenge nonce signed by the digital entity's key.

The present application provides an identity identification method, device and server based on dynamic rasterization management, comprising: tracking a current location of each user to determine a current grid area each user is located; receiving an identification request sent by a service terminal; wherein the identification request comprises first location information and live body biological characteristic information of a target object; determining a first grid area where the service terminal is located based on the first location information; obtaining biological characteristic information of each user with respective current grid area being the first grid area; completing an identity identification according to the live body biological characteristic information of the target object and the biological characteristic information of each user in the first grid area. This application may further simplify the process of identity identification, improve the user experience of the user when performing identity identification, and at the same time may reduce the risk of identity identification.

Transaction-enabling systems including a controller are disclosed. The controller can access a distributed ledger including an instruction set, tokenize the instruction set, interpret an instruction set access request, and, in response to the instruction set access request, provide a provable access to the instruction set.

Embodiments of the disclosure provide systems and methods for verifying digital payments for a payment platform. The system includes a communication interface configured to receive service data associated with a transaction from a terminal device associated with a user of the payment platform. The system further includes at least one processor configured to automatically determine whether an authentication is waived for the transaction based on the received service data and a blacklist generated using a machine learning model. The blacklist includes a list of suspicious users and transaction behaviors. The at least one processor further configured to approve the transaction without requesting user authentication information from the terminal device when the authentication is waived. The at least one processor also configured to request the user authentication information from the terminal device and validate the user authentication information when the authentication is not waived.

There are provided systems and methods for a physical card having one or more location detection modules A physical payment card may include one or more components to limit card reading of card data stored to the card using a location detection chip. The location detection chip may receive power from a source when inserted to a card reader, and may then determine a location of the card, such as a coordinate location of the card or nearby detected device. The location detection chip may determine if this location or device matches authorized locations stored in a memory of the card. If it does, power may be provided to a card chip of the card. The card chip of the card reads card data from a memory of the card and may then output the card data to the card reader.

A method for identification of malicious activity based on analysis of a travel path of a mobile device through multiple geographic areas includes receiving at least three location data associated with the mobile communication device, the first location data comprising indication of the geographic area of the mobile subscriber and a receipt timestamp; determining the actual travel time of the mobile subscriber from the first geographic area and the third geographic area based on a difference between timestamps of the first location data and the third location data; determining a minimum transition time for the subscriber of the mobile device to move from the first geographic area to the third geographic area; and identifying a malicious activity based on comparison of the actual travel time and the minimum transition time wherein actual travel time is less than minimum transition time between the first geographic area and the third geographic area.

A method for providing registrationless payment card security for a payment network that includes maintaining a list of anonymous mobile telephone numbers, which correspond to personal payment card account numbers (PAN). When a card-present authorization for a listed PAN is received, the payment network requests the geolocation of the cell phone of the card holder in real time from the mobile network operator. The mobile network operator determines the geolocation of the cell phone and transmits it to the payment network. The payment network compares the geolocation of the cell phone with the geolocation of the merchant to confirm that the card holder is present at the location of the transaction.

A secure delivery system according to various aspects of the present technology comprises a transport box having a storage space, an environmental control unit, a plurality of electrical contacts, and a deployable receiving tray responsive to automated delivery systems. The transport box fits within an interior space of a delivery box having a GPS receiver that provides a geographic delivery location of the delivery box. The delivery box comprises a plurality of corresponding electrical contacts configured to be coupled to the electrical contacts of the transport box to provide power to the transport box. The delivery box may further comprise an electronic lock that is responsive to a delivery box controller circuit configured to operate the electronic lock.
