But the my vs. the bank's money is the reason I use my credit card almost exclusively for in person and online purchases. If I go to the Kwick-E-Mart, and pull out my PayPass (or other RFID) enabled credit card and someone snipes my credit card number from it as I swipe for cheetos, I'm fine if it's a credit card. They can run up 20k in charges on my credit card and I don't care (even if the credit card company doesn't stop it), I'll call my bank and tell them that they need to fix that, and probably go find a bad guy, also, I'm not paying that.
If they run up 20k in charges on my debit card before I or my bank notices, I am missing $20,000 from my account. Then I have to hope that the bank can and will fix it before my bills are due.
If used properly credit cards are month long interest free loans with no risk if someone steals the loaned money. Debit cards are wooden door to your bank account with a really aggressive, sleepy, deaf hound that you have to sic on the bad guys after you realize your money is gone.
