This is incorrect.
Visa's processes ~$14T in transactions. At 0.2% thats roughly ~$28B in revenue (VISA posted ~$40B in revenue in 2025) versus 2% is $280B in revenue.
EDIT: The 2~3% you're talking is the payment processor fees which get divvy'd out to acquiring processors, acquiring banks, gateways, merchant processing, etc. etc.
