(Charlotte, NC) -- Things are going to change for Bank of America debit card users. The bank will allow only single debit card transactions beginning this summer if the card user has enough money in their account. According to B-of-A, the new policy will help its customers lessen the likelihood of overdrawing their accounts. Chase Bank is instituting a similar policy with its debit card customers, also beginning this summer. The new rules pertaining to debit cards come as banks get set for a new federal guideline to go into effect.
