From a financial website…
“ CREDIT CARDS Credit cards offer consumers the widest fraud protection. By Federal law, a cardholder is only liable for the first $50 of an unauthorized transaction at most, with many issuers offering cards with zero liability. DEBIT CARDS Debit card holders are protected under a different law, the Electronic Funds Transfer Act. With debit cards, users' liability is capped at $50 only if they notify the bank within two days of realizing the debit card is missing. Beyond that, they could be responsible for up to $500 of a crook’s spending spree. And waiting more than 60 days to contact the bank could leave a user stuck paying every cent of the unauthorized charges.”
