Prepaid cards are about to get easier to understand and more secure.

The Consumer Financial Protection Bureau on Wednesday released long-awaited, final rules on prepaid accounts to give consumers federal protections that already are available on checking accounts and credit cards.

“Prepaid accounts are among the fastest-growing consumer financial products in the United States,” CFPB Director Richard Cordray said in a call with reporters Tuesday in advance of the roll-out. “Before today, however, many of these products lacked strong consumer protections under federal law.”

From 2003 to 2012, the amount of money loaded onto prepaid debit cards — typically used to make purchases and withdraw cash from ATMs — skyrocketed from $1 billion to nearly $65 billion, according to estimates by Mercator Advisory Group, a payments research firm.

The rules — which take effect Oct. 1, 2017 — will affect not only prepaid debit cards, but also other prepaid products such as digital wallets and some peer-to-peer transfer apps that hold balances, such as Venmo, PayPal and Square Cash.

“Wednesday’s announcement is a major step forward for this payment product and for the millions of Americans that rely on it,” said Sean McQuay, credit and banking expert at NerdWallet. “While prepaid debit cards have grown in popularity, they’ve been hard for us to recommend, due to their lack of mandatory consumer protections in the past.”

Other prepaid accounts such as payroll cards, student financial aid disbursement cards, tax refund cards, and government benefit cards used to distribute unemployment insurance and child support also will be covered by the new rules, according to the CFPB.

However, gift cards, disaster-relief and health- and transit-related cards won’t be affected.

The rules will give prepaid accounts new federal protections — including requiring upfront, easy-to-understand disclosures on fees and other information — in line with those available on checking accounts and credit cards.

You’ll have the right to dispute errors and fraudulent charges on prepaid accounts, be protected against unauthorized transactions if the cards are lost or stolen, and be able to view account information online or by phone for free, like you can with checking accounts.

Prepaid cards and accounts that offer a credit component, such as a cash advance or overdraft option, will face additional requirements similar to those on credit cards.

The issuing companies must ask you whether you want to opt into any service that lets you borrow money. If you choose to opt in, under the new rules, you’ll be notified via monthly statements of any fees you get charged. You’ll have at least 21 days to repay any overdrafts and other debts before a prepaid company can charge a late fee — and that late fee must be reasonable. This treatment around repayment is a bit stronger than overdraft policies on checking accounts.

“It’s a big win for consumers in all areas, especially [since] consumers will be protected against harmful overdraft fees,” said Thaddeus King, an officer for the consumer banking project at the Pew Charitable Trusts. “That’s the reason that most consumers gravitate toward these cards.”

The nonprofit research group in Washington, D.C., has advocated for better consumer protections on prepaid debit cards for many years.

“We see the rules as very forward-thinking and very relevant in an evolving marketplace,” said Joy Hackenbracht, research officer on the project at Pew.

The Network Branded Prepaid Card Association, which represents the prepaid card industry, has a different view.

“Instead of fostering financial innovation and inclusion, the CFPB’s rule will ultimately limit access to an essential mainstream consumer product that helps millions of Americans,” Brad Fauss, president of NBPCA, said Tuesday.

Fauss added that the new regulations on overdrafts for prepaid accounts may lead companies to drop that feature.

King, however, noted that most prepaid cards don’t offer overdraft services, so that part of the rule won’t affect issuers.

Overall, the rules aim to bring more transparency to a prepaid marketplace that’s been criticized for taking advantage of the unbanked and other financially vulnerable consumers.

“For the longest time, prepaid cards have been an option for those who can’t open checking accounts, but now they’ll be a safe option, too,” NerdWallet’s Sean McQuay said.
