Credit card companies can cancel your card without advance warning

I prefer credit cards to debit cards, due to the consumer protections. If someone steals the credit card number, the issuer is out money, not you. With debit cards, someone can steal your money! But these protections are now leading credit card companies to close what they deem to be "risky" accounts. It is good to have a backup card in case you are the victim of these tactics. .
