In one implementation, a computer-implemented method, executed on a computing device and configured to effectuate a trading platform, includes: maintaining an omnibus (multi-client) cryptocurrency trading wallet for a plurality of clients; and maintaining a segregated (individual-client) cryptocurrency transfer wallet for each of the plurality of clients, thus defining a plurality of segregated (individual-client) cryptocurrency transfer wallets.

According to an embodiment, provided is a method of managing a state after automatically injecting medicine, including: installing, by a first user terminal, a drug injection program received from a management server thereon; receiving, by the first user terminal, at least one from usage data of a drug injection device, a drug injection message, a biometric value measurement message, and a device state message from a controller via the drug injection program; receiving, by the first user terminal, an input of a risk alarm setting information from a user and transmitting the risk alarm setting information to the controller; receiving, by the first user terminal, a risk signal corresponding to the risk alarm setting information from the controller; and determining, by the first user terminal, a manager according to the risk signal, and transmitting a risk alarm message to a terminal of the manager according to the risk signal or a risk management center.

Embodiments provide methods and systems for controlling payment transactions in a payment card using a companion payment application installed on a user device. The payment application and the payment card may be provided by an issuer server. Using the payment application, the number of transactions allowed on the payment card or an amount limit is set for the payment card. The payment application is used to set, reset, change the value of a counter in the card, which determines the number of allowed transactions. When the user attempts to make a transaction at a POS terminal, the payment card reads the value of counter, and if the value is not equal to a threshold value, the payment card exchanges data with the POS terminal and updates the value of the counter. The payment card is precluded from transaction when value of the counter is equal to threshold value.

A user may pick an item from a first inventory location, such as in a lane on a shelf, and may return it another location that is assigned to another type of item. Described are techniques to generate tidiness data that is indicative of whether an item has been returned to an inventory location assigned to that type of item. As items are taken, information about the type of item taken and its weight are stored. When an increase in weight at a lane indicates a return of an item to the lane, the weight of the return is compared to the stored weight of the items previously taken by a user. If the weights correspond to within a threshold value, the type of item associated with the stored weight is deemed to be returned and tidiness data indicative of a tidy return of the item to its appointed lane may be generated.

In an electronic payment system according to an example embodiment of the present disclosure, when a terminal device receives, from a user, an order for filling with energy a vehicle to which energy is to be supplied, it determines whether the balance of electronic money is equal to or greater than a predetermined maximum amount of money. When the balance is equal to or greater than the maximum amount of money, the terminal device causes an electronic money management server to secure the maximum amount of money as a credit amount from the balance. After energy is supplied to the vehicle on the basis of the order, the electronic money management server deducts the cost of the energy supply from the credit amount.

Disclosed are various embodiments for improvements in customer relationship management and point of sale payment processing at remote event spaces. The system, apparatuses, and methods disclosed herein facilitate the transaction processing of credit cards and other payment vehicles in often remote locations where network connections may be intermittent and suffer from frequent disconnects or interruptions of service. The embodiments disclosed operate to detect network events, dynamically adjust to the event space, and processes the transactions on demand. The apparatuses are equipped to facilitate the event environment and are adapted to execute instructions to facilitate the financial transactions.

Methods and systems for fault tolerant token based transactions are described. A user may perform a transaction with a mobile device. The mobile device may be in an offline mode or may be lacking a network connection to servers or cloud devices of a mobile payment system. The transaction may be processed through a transaction device, which may aid in the sending and receiving of transaction data while the mobile device is in the offline mode. The transaction device may communicate with the server or cloud device and the server or cloud device may process the transaction and communicate with the transaction device, which may forward data from the server or cloud device to the mobile device.

Various embodiments herein each include at least one of systems, methods, and software for value transfer between disparate systems. One such embodiment includes receiving a transfer request to transfer a value from a first account provider to an account maintained with a second account provider and including data identifying an individual or entity that initiated the transfer request. This method also includes identifying the second account provider based on data included in the transfer request and generating a request to transfer the value of the transfer request to the account in a format compatible with the second account provider. The method may then transmit the generated request to the second account provider.

A limited use temporary credit account is disclosed. The method includes displaying, on a display of a mobile device, a temporary credit account, the temporary credit account correlated with a newly approved non-integrated credit account, the temporary credit account including: a temporary account number; a temporary expiration date; and a temporary security code. Incorporating a time constraint into the temporary credit account displayed on the mobile device, the time constraint limiting an amount of time the temporary credit account is displayed on the mobile device and limiting an amount of time the temporary credit account is available for making a purchase. Integrating a credit limit reduction into the temporary credit account displayed on the mobile device, the credit limit reduction reducing an available credit on the temporary credit account to an amount less than a credit available on the newly approved non-integrated credit account.

Provided is an electronic cash-based offline transaction method and system. The method includes: receiving, by a back-end server from a smart card, an anti-replay factor generated by the smart card; determining, by the back-end server in accordance with a predetermined algorithm, whether an abnormal transaction occurs on the smart card, generating, by the back-end server when no abnormal transaction occurs, a security information signature by signing security information with a private key of the back-end server, and transmitting, by the back-end server, the security information and the security information signature to the smart card (S2).
