About Us

I’m Darong. I’m a senior software engineer and a specialist in bank integrations. I’ve often received questions from users and merchants like:

• Why did this transaction fail?
• Why this customer card is declined?
• Why did this user fail to deposit?

By the time these support tickets are raised or responded to, the sales have already lost.

Thus, I believe the solution is for merchants to act immediately and win back their customers.

All feedback is welcome. Reach out anytime. I respond to every message.
