Method and system for retry processing of controlled payment transactions

A system for retrying processing of a controlled payment number transaction via a dual processor and a redundant database, comprising:

• a first database of a processing server configured to store a plurality of account profiles, wherein each account profile includes data related to a transaction account including at least an account identifier and one or more account controls;
• a second database of the processing server configured to store each of the plurality of account profiles stored in the first database, wherein data included in each account profile stored in the second database corresponds to data included in the corresponding account profile in the first database, and wherein the second database is a read-only database;
• a memory device configured to store:
• a normal transaction processing queue data structure, wherein the normal transaction processing queue data structure includes a first set of one or more pending authorization requests for which processing is required and a determination associated with each of the first set of one or more pending authorization requests, and
• a priority transaction processing queue data structure, wherein the priority transaction processing queue data structure includes pending authorization requests for which processing is required and a determination associated with each respective pending authorization request, wherein the processing device is configured to process pending authorization requests stored in the priority transaction processing queue data structure before processing pending authorization requests stored in the normal transaction processing queue data structure;
• a receiving device of the processing server configured to receive, via a point of sale device associated with a merchant, a current authorization request for a current payment transaction, wherein the current authorization request includes at least a specific account identifier and transaction data;
• a transmitting device of the processing server;
• and
• a primary processing device of the processing server and a secondary processing device of the processing server, wherein the primary processing device of the processing server and the secondary processing device of the processing server are configured to:
• responsive to an unsuccessful attempt to determine, by a primary processing device of the processing server, approval or denial of the current authorization request for the current payment transaction based on the one or more account controls included in a corresponding account profile stored in the first database where the included account identifier corresponds to the specific account identifier:
• storing, by a secondary processing device of the processing server in the memory device in the priority transaction processing queue data structure, the current authorization request for the current payment transaction;
• and
• determine, by the secondary processing device of the processing server, an approval or denial of the current payment transaction stored in the priority transaction processing queue data structure based on at least the one or more account controls included in an account profile stored in the second database where the included account identifier corresponds to the specific account identifier and the transaction data included in the received current authorization request;
• wherein:
• the secondary processing device of the processing server is configured to process the current payment transaction based on the determined approval or denial, wherein the processing, by the second processing device of the processing server, of the current authorization request for the current payment transaction stored in the priority transaction processing queue data structure occurs before processing any of the pending authorization requests stored in the memory device in the normal processing queue data structure;
• and
• responsive to determining that the current payment transaction is to be approved, the transmitting device is configured to transmit the current authorization request to a financial institution associated with the transaction account related to the account profile that includes an account identifier corresponding to the specific account identifier.
