Yes, it is worth it. Cash, IMHO, is a major pain in the ass. I don’t use my debit card for anything except cash, and I don’t get my cash from anywhere except from the ATM physically located at my bank branch (once every few weeks); anyone trying to put a skimmer on one of those is going to recorded from about five different camera angles.
Compared to cash, credit cards are amazingly convenient. Cash? You’ll walk inside to pre-pay, then realize you forgot what pump number you’re on. So you walk back outside, get the number, then go back inside and get in line behind four other cash customers, three of whom take their sweet-ass time trying to figure out which scratch-off lottery tickets and cigarettes they want to buy. Then you lay down $40 and ask them to kindly activate pump #5. Then you walk back outside and pour fuel, but you find that your tank’s full up at just $33.25. So you go back inside, get in line behind another three lottery-playing putzes, and pick up your change. Then you walk back out and get on your way.
With a credit card, I can be done fueling up before you finish prepaying with cash.
Risk? What risk? For credit card, you are legally liable for only the first $50 of fraudulent transactions after you become aware that your card has been compromised.[sup]*[/sup] HOWEVER:
Credit card issuers have become pretty good at spotting fraudulent activity. My wife and I have each had an AmEx card defrauded, and in both cases AmEx spotted the problem and alerted us before we were aware of anything. In both cases we weren’t liable for any of the fraudulent charges.
Even though you’re legally liable for the first $50 in fraudulent charges, your continued credit card activity is worth a lot more than that to the bank. If you threaten to cancel the card, they will happily eat that $50 on your behalf in exchange for your continued patronage.
The risks associated with carrying enough cash to make a cash-based life relatively convenient are greater than the risks associated with using a credit card for as many of your purchases as possible.
[sup]*[/sup] Similar liability-limiting rules apply to debit cards if you report fraud promptly, but the risk there is that it might take precious time to get your money back; contrast this with the credit card bank, where the loss/recovery is theirs to deal with.
