Debit cards tend to overdraft, and banks made more than 44 Billion last year.
Credit cards charge the merchant 1%, and almost half of the people that use them carry a balance and pay interest.
Which is more profitable – $35 overdraft fees, or interest on 40% of the population.
Keep in mind – almost 60% of people have never carried a balance or paid interest.

I mean, other than ATM charges, how do they profit from debit cards? since they don’t operate with interest and take money directly off of your account?
