Why are credit cards preferred in the US?
Credit card fraud protection (by law), credit card cash back programs (provided by most CC issuers), and debit card fees (commonly imposed by the merchant). The crux is that with CC transactions, a small percentage is remitted to the issuing bank.  Since the banks are already making money hand over fist on CC's, they incentivize people to use them. CC security is also lax because the merchant is responsible for fraudulent charges instead of the bank.  If the merchant fails to check a signature, they are held liable for all charges if the card holder reports a fraudulent transaction.
