Hana Bank said on March 26 it launched the financial sector's first "remote AI export document writing guide" service.

The service is an AI-based system that supports exporting companies in preparing key documents needed for letter-of-credit transactions, including commercial invoices, packing lists and bills of lading, in line with letter-of-credit terms and international standards.

Hana Bank and the Hana Financial Group Convergence Technology Institute jointly developed it. The system uses AI-OCR and natural language processing to analyse letter-of-credit conditions and reflect them in the document preparation process.

The bank expects it to reduce the risk of document defects in letter-of-credit transactions and lower the likelihood of delays in export payment settlements. It also built the AI engine on the bank's internal servers to secure information security stability.

Previously, exporting companies had to prepare documents themselves and visit branches, but the service provides advance guidance through corporate internet banking, enabling remote processing.

A Hana Bank official said the service was designed to ease the workload for small and medium-sized exporting and importing companies in the early stages and strengthen on-site support. The official said the bank would continue to advance its export and import finance services based on technology-driven convenience.
