Mercantile Website Security

Mercantile Bank has purchased an Extended Validation (EV) SSL Certificate for the website, which provides an additional layer of protection. This enables customers to trust that the Mercantile Bank site is what it claims to be, rather than a fraudulent mirror site operated by perpetrators of phishing schemes. This is new technology designed specifically to address widespread phishing schemes that have been targeting the financial services industry.

When you visit a site with this new EV SSL Certificate, new high-security browsers will trigger the address bar to turn green and display the name of the organization listed in the certificate as well as the Certificate Authority as shown below:

Mercantile Internet Banking Multifactor Authentication

Upon your initial login into the online banking or mobile systems you will be presented a Temporary Access Code (TAC). The TAC can be received as a phone call or text.
