AI Technical Summary

Problems solved by technology

[0003] 1. The current business model of cross-border payment business will lead to long payment paths and low payment efficiency due to multiple agent banks;

[0004] 2. Due to the time difference between the remittance bank and the beneficiary bank and the correspondent bank, or the correspondent bank is on a holiday, the time consumption of cross-border payment will be increased

[0005] 3. Customers need to pay fees to the agent bank for remittances, which will lead to high costs;

[0006] 4. Based on the agency model of SWIFT, the account is written off through the statement at the end of the day, and the account is written off once a day, so the efficiency of the account write-off is low

[0007] 5. The remittance bank cannot know the transaction status in time. SWIFT is currently developing the query service through the level-by-level feedback of the GPI service, but there is also time consumption and real-time query cannot be achieved.
