Routing Checker Pro II validates ABA routing numbers via algorithm and traces bank information via built in database. If found, populates a results window and allows record to be printed. New feature also allows for export of database to text file for importing into other database structures. Also validates credit cards by type. Database updates included for 1st year [approx 1 update per month]. Annual updates available after the first year for very nominal fee. Helps reduce fraud and entry errors in check printing software resulting in bounced checks.
