The Chex System is a computerized database shared by most banks, credit card providers and other financial institutions. Its purpose is to track and report about people and businesses who write bad checks, close bank and other accounts with a balance owing, or commit any type of fraud. The Chex System is not a legal enterprise, but it can be used as a basis for denying credit to a person or business. It can also be used to deny a person or business from opening new accounts. Generally, when a person or business is listed on the database, if they cure the situation the party who listed them in the database will update their records to show that the person or business in now in good standing. If this does not happen, a person or business may be listed for seven years as not in good standing.
