No. It simply means that if you deposit on Stars and your echeck is not good, they will report this insufficient funds transaction. With echecks, about the only way to do it is on a weekend when you have other transactions pending.

However,

I think everyone that uses a checking account for this kind of thing or even for having say their apartment rent deducted should have 2 checking accounts:

Account 1 is the account for echecks. It's the account for poker cashouts; it's the account you pay the IRS from; its the account you have the apartment take out rent every month, etc.

You also keep almost no money there.

Account 2 is where you have all your money and you routinely send money to account 1 to pay for stuff.

This is how I do it and it keeps any unscrupulous folks from accessing my account (if they do they only get a few bucks).

That looks like good advice T-rod.
