A reader just asked me about ChexSystem and how to review one's ChexSystem report. Many banks use ChexSystem in the account application process. It's design to flag those who have abused banking accounts in the past (i.e. bounced checks, unpaid fees, etc.) However, it has also been used by some banks to reject those who have too many recent ChexSystem inquiries (have opened too many accounts).
Like your credit report, you can get a free copy of ChexSystem each year from ChexSystem Customer Assistance
. For more info on ChexSystem, refer to this MyMoneyBlog post
