Some users have auto-fill, or auto-complete, set up on their browsers. When entering credit card information for payment, the Card Security Code auto-fills as a password field. When the donor or registrant attempts to submit the transaction, it does not go through, as the Card Security Code is incorrect.
NOTE: For additional information, please consult the Help or Support resources provided within the web browser. Configuration of optional web browser features is beyond the scope of Blackbaud Product Support.
