A method and system include providing a user interface associated with an issuer of an account; receiving, at the user interface, a request to generate a token associated with a user account; generating at least one token associated with the user account; authenticating one or more elements associated with the user account, wherein authentication may be one of prior to and subsequent to the generation of the at least one token; and receiving the at least one token. Numerous other aspects are provided.

A computerized system for activating, issuing and otherwise managing transactions and activities pertaining to stored-value cards over a communications network. A central information database is provided for storing stored-value cardholder and card purchaser information received directly from respective stored-value cardholders and card purchasers PCs through a universal central processor via respective communication gateways. The central processor is coupled for communication realtime to multiple unaffiliated stored-value card processing networks normally operated by respective hosts. Each network includes a stored-value card processor coupled to a stored-value card database and multiple respective merchant communication devices. The central processor is programmed for managing the activation and issuance of transactions and activities for the stored-value card through the respective unaffiliated networks. The universal central processor is programmed to issue the stored-value cards directly to the cardholder or card purchaser by download over respective communication gateways. The universal central processor is further programmed for reporting the card activations, issuances, transactions and activities to the cardholders and the merchants thereby providing a universal management system.

A system, a method, and a program for providing a financial transaction by a virtual card number, a virtual card number generating device, and a virtual card number verifying device are provided. The method includes receiving, by a virtual card number verifying means, a virtual card number provided from a virtual card number generating means, extracting, by the virtual card number verifying means, a plurality of detailed codes included in the virtual card number, searching, by the virtual card number verifying means, for a storage location of a real card number based on the plurality of detailed codes, and proceeding, by the virtual card number verifying means, with the financial transaction or requesting, by the virtual card number verifying means, to proceed with the financial transaction using the real card number extracted from the storage location.

Flexible fiat and cryptocurrency Payment Services (FfcPS) are disclosed for travel and credit cards. This invention applies to U.S. Dollar, European Euro and other fiat, and Bitcoin, Ethereum and other cryptocurrencies. Merchants that use this invention would add a new item to their (room) key cards and credit cardsa Merchant cryptocurrency wallet public address Quick Response (QR) Code (Merchant QR Code).
