It’s important to note the difference in how you will be reimbursed for credit cards vs. ATM or debit cards. For a credit card your loss is limited to $50.
However, for an ATM or debit card the loss is limited to $50 if you notify your institution within 2 business days after the card is lost or stolen.
Keep in mind that the loss could be up to $500 if you do not tell your bank within two business days of the loss or theft.
If you do not report unauthorized transfers within 60 days of your statement being mailed to you, you run the risk of having unlimited loss on transfers made after the 60 days.
