Transaction certification management system, transaction certification management apparatus, and transaction certification processing method

A transaction certification management apparatus, comprising:

• a communication interface configured to send and receive data over a communication network;
• a storage device configured to store data;
• a processor configured to:
• receive encrypted data via the communication interface from a first terminal apparatus, the encrypted data including transaction certification data generated and output by a transaction processing apparatus, the first terminal apparatus being configured to read the encrypted data output by the transaction processing apparatus,
• acquire a first user identifier identifying a user of the first terminal apparatus sending the encrypted data,
• store the transaction certification data of the encrypted data in the storage device, the transaction certification data being correlated to the acquired user identifier,
• receive, via the communication interface, a second user identifier for a user requesting a transaction certification, and
• transmit the transaction certification data to a second terminal apparatus associated with the second user identifier.
