Financial Analyst

She earned her Bachelor’s degree in Accounting from Central CT State University in 2001 and went on to build a career spanning more than 20 years in regulated private water utilities.

The Red Flag feature has been improved! Now you can set your system to not print a badge for any visitor record that has been previously marked with a Red Flag. The attendant will be prompted to redirect the visitor according to your security protocol.
It’s easy and free to activate this feature. Simply call us and ask for “Red Flag, No Badge” to be turned on. Once it’s on, the above pop-up will come up when a red flagged visitor comes back. No badge will print and the attendant will need to follow the facility’s policy for handling red flagged visitors.
The flags and notes only show to the desk attendant, not the visitor.Â
Please contact eVisitor Support with any questions on how to use Flags in your system.Â
