Get ready for some changes to your debit card account. As a result of last year's financial reform law, large banks will be slapped with a fee limit on debit card transactions. Beginning in July, banks such as Chase, Wells Fargo, and Bank of America will be prohibited from charging retailers more than 12 cents each time a customer swipes their debit card, down from a current average of 44 cents. Banks stand to lose billions of dollars from the rule change, and are lobbying furiously for it to be scrapped. But debit card holders may well be affected, too. Here, five ways the fight could affect you:

1. No more rewards
Debit card holders are used to rewards programs that give them airline miles, shopping deals, and sometimes even cash back. But some banks, including Chase, Wells Fargo, and PNC, are rolling back the customer perks to offset their own expected losses. Chase will bring its rewards program to a complete halt. Others are expected to follow suit.

2. A possible $50 cap on debit card transactions
Some banks are rumored to be considering a more drastic method of stemming losses from the fee limit: A cap on debit card transactions, perhaps as low as $50. Card issuers believe this will encourage consumers to pay with credit card, cash, or checks instead of using their debit card. This could be disastrous for the consumer, says Gino Bona at Fearless Revolution. Putting "obstacles" in front of debit card use would "drive consumers back to credit cards" and the "reckless spending" that comes with them.

3. Higher debit card fees
Some banks already slap monthly charges on debit card checking accounts, but these could rise exponentially after the fee limit is enacted, says Jane Bryant Quinn at Moneywatch. Analysts say consumers could see new, monthly service fees, a possible "increase in the number of times you have to use your card to qualify for a no-fee checking account," or even transaction fees of up to 25 cents on every purchase. Remember, "if your big bank does impose fees you don't have to put up with it." Institutions such as credit unions and community banks should stay "fee-free."
4. A $10 debit card minimum
For the first time, the financial reform law allows merchants to set a $10 minimum limit on debit or credit card purchases. That should theoretically reduce the number of transactions, encouraging customers to use cash or checks instead.

5. Lower prices in the stores
The fee limit is unquestionably good news for retailers, says Moneywatch's Quinn, for whom debit and credit card fees have traditionally been one of the highest costs. So will retailers "actually pass some of these savings on" to you, the customer? Some might. "In highly competitive businesses, such as grocery stores, consumers should benefit." But industries with "pricing power," like luxury clothes brands or high-end technology, probably won't.
