Do you have a prepaid card in your wallet? They’re popular because they’re convenient. You, your employer, or someone you know loads money onto the card, and you use it in a manner similar to a credit or debit card. In the past, prepaid cards lacked some consumer protections. Now, the Consumer Financial Protection Bureau has finalized rules that limit your liability for unauthorized charges to $50, as long as you notify the card issuer promptly. The new rules also include requirements for clear explanations about fees, and free access to account information.
