Abstract: The invention provides a method for application of statistical methods to rank various currencies in a payment system, wherein currencies are created in the same pattern but have different parameters and different user-acceptance rates, which together are used for the assignment of a rating to each currency and ranking of the currencies according to the ratings. Currency ratings are a function parameters, each parameter being the numerical value of a time series data set: amount of currency in circulation, the number of times a currency is used in transactions, number of different users accepting the currency, back-up level (redeemability) of currency and market value of the currency. These five main parameters can be combined so as to arrive at independent variables, each independent variable having a different weight in the determination of currency ratings; the weights (coefficients) themselves can be customized by the operator of the system.

Abstract: The invention provides a method for information exchange in the process of electrical appliance lease. Appliances available for lease are registered in a cloud environment where each appliance is associated with the following information: type (what kind of appliance it is), owner (who is the lessor), holder (who is the current holder), status (is the appliance available for lease), condition (current condition of the appliance), price (lease price of the appliance), rating (rating of appliance) and location (GPS data). Users interact with each other through a server which operates the system. The server receives and executes user action requests, transfers information between users and measures lease time and total price. The server is coupled to a database used for storing data for appliances, users and lease contacts. The processed data is shared in a cloud storage, accessible to the users.

Abstract: The invention provides a method for lending/borrowing in a web-based payment system with a multitude of currencies, where a public currency serves as a universally accepted medium of exchange, while private currencies, issued by commercial entities—represent obligations of the issuers to provide certain amounts of goods and services. When a potential commercial borrower wants to receive a loan, the centralized authority (the lender) issues, against collateral, a certain amount of new, public, universally accepted currency units into the borrower's account. The borrower issues to the centralized authority an equivalent amount of his private units plus the agreed upon units of interest, which units mature (get activated) gradually over time, at each loan repayment due date. Upon maturity a unit of the matured private, commercial currency can be redeemed by the lender for goods and services of the borrower, or just released into circulation within the money system.

Abstract: The invention provides a method for optimum quantity of money supply in a monetary system, implemented in a web environment with a multitude of users—individuals and legal entities, transacting with each other within a centralized authority, via units of virtual currency. The method is based on the calculation of consumer price index (CPI) in the monetary system and a negative charge on each unit of the currency (demurrage). In order for the CPI to be calculated all financial transactions in the systems are calculated and metadata is extracted in real time for the average price of certain goods and services in the system for a predefined period of time. The changes on the CPI are reflected on the demurrage where signals of inflation increase the demurrage level and signals of deflation decrease it. Optimum quantity of money is achieved through balance between money supply and demurrage.

Abstract: The invention provides a payment system which can be implemented in a web environment, where users are entitled to generate their own currency in a certain pattern. Digital wallets for the users are created and managed through a centralized server which acts as an intermediary in the currency generation, transactions and extinguishment. The currency units generated by the users compete with each other and with a centrally issued (reserve) currency, generated by the operator of the system. Each user is provided the option to create a personal filter for the payments he/she receives in the system based on one or more of the currency features. A money market where all units of currency can be traded is also provided in order to facilitate the value exchange in the system and measure the exchange rate of user generated currencies against the reserve currency and/or against other currencies.

Abstract: The present invention provides in at least one embodiment, a payment system with a method for distributed money supply. The system is implemented in a web environment where users interact with each other and a central authority with data processing devices through a network. Mediums of exchange in the system are public and private currency units. Public currency units are created by the operator of the system—a central authority while private currency units are created on the initiative of the users where each user is entitled to request the creation of his own currency. Currencies and currency units are managed by a server coupled to a database. The database stores data for every user and every currency. Currency data is stored in separated pieces of memory in the database—accounts. The server operates the currency issuance, transaction and redemption through the management of the currency accounts in the database on request of the users.
