Even the simplest words can use a little clarifying from time to time. Transaction: to carry on or conduct an activity to a conclusion or settlement. Process: to convert or change a thing from one thing to another. Think about what you are doing in transaction processing.
You are changing the ownership of a product from one person to another via a transaction. Then you are changing the ownership of the funds for the item from one person to another by sending the credit card information and amount to a middleman who will then decipher it and send it back to the bank that owns the credit card. This bank will then send the money back to the middleman who will deposit it into your bank account.
It is amazing that the initial step can be completed in less than a minute, and the final “process” will deposit the funds into your bank account within a few days.
