Abstract: |
According to some embodiments of the invention, both open loop and closed loop processing may be implemented by a transaction processor. For general, unrestricted transactions, the transaction processor may direct authorization to an open loop primary authorizing entity associated with a primary account number (PAN). For restricted transactions, the transaction processor may determine the appropriate closed loop authorizing entity (e.g., a transit agency, an insurer, a retailer, etc.). The transaction processor may further create an entry in a multi-access blockchain evidencing the transaction on the closed loop or restricted account with that authorizing entity. Thus, the multi-access blockchain may be kept up-to-date, allowing the closed loop authorizing entities to verify transactions and account balances instantaneously. |
