MySDCars and EPath security updates

MySDCars and EPath will soon undergo a security update in order to further protect our users’ personal information.

The update, which will be done to meet industry standards for making credit card transactions online, will go into effect no later than June 20. Many users will not see any changes after the update—depending on the version of the internet browser (i.e Google Chrome, Internet Explorer, Firefox, Safari etc.) they utilize.

Users with older internet browser versions might not be able to access some secure sites. Compatibility information can be found below.

The update is taking place in compliance with a recent review made by South Dakota’s Bureau of Information and Telecommunications (BIT). BIT reviews industry standards on a quarterly basis, ensuring that all of South Dakota’s e-services are in compliance and offer optimal security for our customers
