When credit card transactions "downgrade," it means that they failed to meet criteria for the "target" interchange category. In practical terms, it means your business paid more to process that transaction than was necessary. Non-qualified is a "downgrade" category. Note: "Standard" as an interchange category still applies in limited circumstances; specifically, Visa uses it for international commercial transactions. When a card issued outside the US is used at a US business, and that transaction fails to meet criteria for its target category, it will be charged at the Commercial Standard rate. See our article on Commercial Standard for more info.
