<prompt> Human: Just wondering if Im missing something but is there a reason why someone would want both a credit card and a debit card? I have an ATM card which I use to withdraw money from ATMs when needed and a credit card for items I would buy with plastic. Why would someone have both a credit card and a debit card?  <response>: A lot of people dont or shouldnt trust themselves with credit cards. For them, its probably better to use a debit card even if they also have a credit card available to them.Some debit cards do have rewards, though. Sometimes those rewards are better than credit cards though it seems like they generally have more hoops to jump through.I only have a debit card because my ATM card is one. Ive only ever used it at the ATM.
