A federal judge has certified a class of U.S. payment-card issuers challenging transaction fees they paid to Apple for Apple Pay, turning a lawsuit brought by three credit unions into a potentially much broader dispute over mobile-wallet access and issuer costs.
U.S. District Judge Jeffrey S. White issued the order on September 23 in Affinity Credit Union et al. v. Apple Inc., case 4:22-cv-04174 in the Northern District of California. The class covers all U.S. entities that issued an Apple Pay-enabled payment card and paid Apple a fee for a transaction on that card.
The ruling does not find that Apple monopolized a market, charged unlawful fees or owes issuers damages. Class certification determines that the claims can be litigated collectively because common questions predominate; the credit unions still must prove their antitrust case.
Uniform issuer fees became the common issue
Affinity Credit Union, GreenState Credit Union and Consumers Co-Op Credit Union allege that Apple restricted rival mobile wallets’ access to the iPhone’s contactless-payment functionality while charging card issuers for Apple Pay transactions. They contend that the combination protected Apple Pay from competition and enabled supracompetitive issuer fees.
According to the plaintiffs’ allegations reported by AppleInsider, issuers pay Apple 0.15% of the value of Apple Pay credit-card purchases and half a cent for each debit transaction. The plaintiffs compare those charges with mobile wallets on Android that they say do not impose transaction fees on issuers. Those comparisons remain disputed elements of the case, not judicial findings on the competitive price.
White found that central questions can be answered with common evidence: the relevant antitrust market, whether Apple possesses monopoly power, whether its conduct harmed competition and whether issuers were affected. The order says Apple uses one fee for credit transactions and one for debit transactions across the proposed class. If plaintiffs prove those prices were supracompetitive, the judge wrote, the uniform structure could establish classwide impact.
The court also found a class action superior to potentially thousands of separate lawsuits. The plaintiffs estimate that the class contains thousands of institutions, and the order says Apple did not contest numerosity.
Apple’s expert challenge was rejected, not its merits defense
Apple asked the court to exclude testimony from plaintiffs’ economist Christopher Vellturo. His proposed analysis compares Apple Pay issuer fees with a claimed competitive benchmark of zero in other mobile-wallet markets, then uses the difference to model damages.
The judge denied that request. The order says Vellturo used accepted antitrust tools, including a market-definition test and a yardstick damages model, and that Apple’s objections went to the weight of his conclusions rather than the admissibility of his methods. Apple remains free to challenge his assumptions and conclusions through contrary evidence and cross-examination.
That distinction is important for issuers assessing the ruling. The court allowed a common damages framework to be presented; it did not endorse the proposed calculation as correct or award repayment. Plaintiffs’ lawyers say the suit seeks reimbursement of issuer fees and an injunction against the challenged practices.
The mobile-wallet access question has changed since filing
The litigation began in 2022, when the plaintiffs alleged Apple Pay was the only tap-to-pay mobile wallet permitted to use the iPhone’s near-field communication hardware for point-of-sale card transactions.
Apple’s current developer documentation says iOS 18.1 introduced APIs that let authorized developers provide secure contactless transactions through compatible iOS apps. Eligible apps can be selected as a user’s default contactless app. Access requires an Apple agreement, an entitlement and compliance with eligibility, security and regulatory conditions.
That policy change may affect the scope of any prospective remedy, but it does not by itself resolve claims about fees already paid or prove that current access terms create effective competition. The certified class is defined by card issuance and payment of Apple Pay transaction fees, not by whether an issuer has built or sponsored a competing wallet.
What issuers and payments partners should watch
Card issuers that enabled Apple Pay and paid transaction fees should preserve relevant contracts, fee records and transaction data while the case proceeds. Class notice, any opt-out process and the precise class period are procedural matters that will require close review when the court addresses them; the certification order does not supply a final recovery formula.
For wallet providers, processors and issuer technology vendors, the dispute highlights the commercial importance of control over a handset’s contactless-payment interface. The eventual merits analysis could examine not only posted transaction fees but also whether technical access, entitlement requirements and commercial terms permit meaningful wallet competition.
The next phase still carries substantial uncertainty. Apple can continue contesting market definition, monopoly power, anticompetitive conduct, injury and damages. Certification materially increases the scale and leverage of the litigation, but it is a procedural advance for the plaintiffs—not a final judgment against Apple.
