What are the reasons to get more than one credit card?
Another good reason: if you have to replace a card due to damage, loss, or identity theft it's nice to have a backup you can use until the new card for your primary account arrives. I know folks who use a secondary card for online purchases specifically so they can kill it if necessary without impacting their other uses, online arguably being at more risk. If there's no yearly fee, and if you're already paying the bill in full every month, a second card/account is mostly harmless. If you have trouble restraining yourself with one card, a second could be dangerous.
