There is NO check float anymore. All Banks whether directly or indirectly use Check21 meaning any check you write posts within one hour to one day at most. Banks that are equipped directly to optically scan the check at the teller window clear that check in an hour if it's from another bank that is also Check21 equipped. But every Bank has to be Check21 equipped so smaller Banks or Banks that won't spend the money batch process though a Check21 middle man at the end of the day.
What does this mean?
It means when you write a check it'll bounce right away if the funds are not there.
How does it work when someone writes you a check? Then the Banks fall back on fraudulent laws that say they can wait X amount of days before giving you your money. Just like ACH takes 2 days - it's a huge load of BS when they do this.
