The Federal Reserve Board regulates debit card interchange fees in the U.S. through Regulation II, which was established by the Dodd-Frank Act's Durbin Amendment in 2010. This regulation caps fees for large financial institutions ($10B+ in assets) to ensure they are "reasonable and proportional" to the costs of processing transactions.
Overview of the US payment regulatory landscape
At the federal level, agencies like the Federal Reserve, the Consumer Financial Protection Bureau (CFPB), and FinCEN set broad rules to protect consumers, ensure financial system stability, and stop financial crimes.
The Durbin Amendment, part of the Dodd-Frank Act, limits debit card transaction fees to 21 cents plus 0.05% of the transaction value. Only financial institutions with assets over $10 billion are subject to these limitations, offering exemptions to smaller institutions.

To stop any reoccurring transaction on your debit card, you must contact the merchant (company) directly to make other payment arrangements.
Debit cards and chargeback
Debit card payments and purchases aren't covered by section 75 of the Consumer Credit Act. But if you don't get something you have paid for by debit card, and the firm is refusing to refund you, you can ask your bank to 'reverse the transaction' and get your money back via chargeback.

Yes, it is generally illegal for U.S. merchants to charge an extra fee (surcharge) on debit card purchases, with major card networks prohibiting it, reinforced by federal law (Durbin Amendment) and various state laws, though some states have specific bans or restrictions, making it a complex area where merchants often illegally pass on costs as surcharges or convenience fees.
The average processing fee for debit card transactions is 34 cents in interchange plus your processor's markup.
On average, cardholders have between a 60% and 75% chance of winning a debit card dispute. You are more likely to win a debit card dispute if you challenge an unauthorized charge, or have compelling evidence that a purchase resulted in damaged, delayed, or missing goods.

The 15/3 credit card payment method is a strategy to potentially boost your credit score by making two payments per billing cycle: one about 15 days before your statement closes (to lower reported utilization) and another around 3 days before the payment due date (to cover the rest and avoid late fees), though its actual impact on credit scoring is debated. It works by keeping your reported balance lower when the card issuer reports to bureaus, but experts note the specific timing isn't magical, and focusing on the reporting date is key.
They include billing errors, unauthorized charges, and claims that goods or services were misrepresented, defective, or not delivered.
The 2/3/4 rule is a guideline, primarily used by Bank of America, that limits how many new credit cards you can get: no more than 2 in 30 days, 3 in 12 months, and 4 in 24 months, helping to prevent over-application and manage hard inquiries on your credit report. While not universal, it's a useful benchmark for responsible card application, though other banks have different rules (like Chase's 5/24 rule).
Contact Your Credit or Debit Card Company
You have to tell your credit or debit card company about any error you're disputing within 60 days of when the first statement with the charge was sent to you.
