Low APR credit cards are much more prevalent than in years past. Competition is stiff and credit card financial institutions offer many nice perks, rewards, points, low annual percentage rates (APR) and other inducements.

They want to capture new customers who've never had a credit card but also those who already have a credit card and might like to save money by transferring that card's balance on to their new low APR credit cards.

Of course, there is nothing lower in an APR than zero - and those exist too, although sometimes for a limited time period.
