Interchange: The Fee Structure That Shapes the Industry
Every card fee argument eventually reaches interchange: the fee the merchant's side pays to the cardholder's bank on every transaction. This lesson decomposes the merchant discount rate, explains why rewards cards exist and who really funds them, covers the EU caps of 0.2 and 0.3 percent and their loopholes, and shows why the same purchase costs a merchant triple on a corporate card.

This lesson builds the payment foundation: the five parties in every card transaction, the authorization-capture-clearing-settlement path, who really pays interchange, why card-not-present fraud shapes everything, and the tokenization idea that agent payments are built on.
