Welcome to Payments Domain (Dot) Calm 😊

I am Santosh Rajagopalan, a payment enthusiast. I firmly believe that the best way to learn is by sharing the knowledge I have. My current occupation as a Business Analyst in the software industry has put me on a learning trajectory in Payments domain.

Every day there are new software engineers joining this ever-growing ever-changing domain. I thought I could share whatever I know about payments via. a series of articles. Please feel free to post any questions you might have on these articles as it would add value to me and other readers.

Once again welcome. As a friend of mine once said, “the world is small, and the payments industry is even smaller”. Please join this community and enjoy reading.

Can you please help me with cross border remittance process flow?

Could you please explain difference between Void, Reversal & Refund transactions? Thanks.

From the scope of this blog, I will attempt to answer these questions as best as I can.

These are terms associated with card payments and I request you to follow my blog cardsdomain.com for further info.

From an A2A payments perspective, we have 2 terms that are commonly used. Reject and return.

Reject – When the payment is rejected by the next party in the chain. This party can be a CSM or Another bank. Payments are rejected if accounting has not taken place.
Return – Here, accounting would have taken place in the CSM/Receiving bank and then the money would be returned to us.
