The problem here is "street" definitions vs. technical ones. Banks run NOW (and often MMDA) accounts on their DDA systems. And many banks refer to their NOW accounts as "checking" accounts (I've seen one bank that calls theirs "Interesting Checking"). Consumers think of NOW accounts as checking accounts, rather than savings accounts, which is technically what they are.
So bankers frequently refer to anything on their DDA systems as DDA accounts, whether or not they earn interest.
Technically, DDA means Demand Deposit Account, and only includes non-interest bearing checking accounts and a few odds and ends in the definitions in Regulation D, ยง204.2.
And so far, it's illegal to pay interest on a demand deposit account.
