Simple which is still in beta is a prepaid account but they don't want anyone to know that so despite being prepaid they will argue to the point of sounding stupid that they are not prepaid.
Here from their own account terms is where THEY TELL YOU IT's PREPAID.

Despite this Simple uses a front end risk eliminator - Andera to cull out customers who may present some risk to them despite the fact that it can't overdraft.
Maybe since they allow $200 on a check before it clears they are eliminating that risk? No because they do not ALLOW everyone to use remote check deposit - just like a Bank.
Here on their own Twitter page customers complain they cannot rent a car even with a deposit because the BIN code on the card says it is what it is - PREPAID.
