In a move that may send you bouncing all the way to the bank, the Check 21 Act takes effect on October, 28th. Legislation intended to bring banking into the 21st century, Check 21 allows banks to process checks electronically.
While there are many complicated implications of this, the main thing you need to know is checks that you write may clear a lot faster. And be sure to check your bank statements, as some checks may get paid twice (once the conventional way, and once the electronic way).
Gone are the days of writing check beyond your available funds, counting on the check clearing time to save the day. Isn't technology wonderful?
