Surcharging Wins, AI Commerce Risk, and the Illinois Interchange Fight

Four items this week cover merchant cost reduction, AI-driven purchasing risks, debit fraud verification, and federal preemption of state interchange law. Together they point to cost pressures and infrastructure gaps as active concerns for U.S. operators. The Illinois interchange case is worth tracking, as its outcome could shape card fee legislation in other states.

## Industry moves

**BlueSnap: Surcharging offset nearly $400,000 in card costs for one merchant**

BTR, a truck-rental company, offset nearly $400,000 in annualized card acceptance costs by adopting BlueSnap's credit card surcharging program, per Digital Transactions (https://www.digitaltransactions.net/payroc-snags-btr-for-its-credit-card-surcharging-platform/). Surcharging passes processing fees to cardholders rather than absorbing them as a merchant expense. State-level rules on surcharging vary, so verify your state's requirements before enrolling.

**Worldpay: AI agent purchasing could expose checkout and fraud gaps**

A Worldpay survey of 8,000 consumers across 8 global markets, covered by Finextra (https://www.finextra.com/blogposting/31835/why-agentic-commerce-could-expose-major-weaknesses-in-merchant-infrastructure?utm_medium=rssfinextra&utm_source=finextrafeed), examined AI agent-driven purchasing, where software completes transactions on a consumer's behalf. Standard checkout, fraud, and authentication flows are built around human behavior. Non-human transaction patterns may not fit those assumptions. Merchants expecting AI agent traffic should audit their fraud and authentication logic.

**Fiserv: Debit card ownership verification added via Experian Link**

Fiserv is integrating with Experian Link's debit card ownership verification service, per Digital Transactions (https://www.digitaltransactions.net/fiserv-signs-up-for-experian-links-debit-card-ownership-checker/). The tool confirms at checkout that a card belongs to the account holder. Merchants on Fiserv may see lower fraud rates and fewer returns as a result.

**OCC files brief to block Illinois interchange law**

The OCC filed a brief asking a federal judge to block Illinois's law regulating interchange fees, arguing federal rules preempt it, per Payments Dive (https://www.paymentsdive.com/news/occ-aims-to-derail-state-card-law/821079/). The OCC has already issued a preemption ruling on the law. Interchange is a direct operating cost for U.S. merchants. The court's decision could influence whether other states pursue similar card fee legislation.

## The takeaway

Track the Illinois interchange case: a ruling on OCC preemption will signal how other states approach card fee legislation. If you are on Fiserv, ask about the Experian Link debit verification rollout. If your state allows surcharging, model the cost offset against BlueSnap's BTR result.
