Online Banking Security

Commercial Bank will never send an email message requesting confidential information such as account numbers, PIN Numbers or Passwords. If you should ever receive such a request, contact Commercial Bank at (620)421-1000 immediately.

With the proper safety measures in place, your Commercial Bank Internet Banking transactions remain confidential and safe. The following measures have been taken to ensure your privacy:


Secure access and verifying user authenticity:

Unique ID and Password
In order to access Commercial Bank Internet Banking, you must enter a unique User ID and Password


Account “Pseudo” names

Commercial Bank does not display your account numbers over the Internet. Instead, we allow you to choose a “pseudo name” for each of your accounts. For example: Home Checking, Judy’s Savings, etc.


Automatic Log Off

If you are logged on to Commercial Bank Internet Banking and do not use it for 10 minutes the system will automatically log you off.


Password Lockout System

To keep unauthorized individuals from accessing your account by guessing your Password, we have instituted a Password lockout system. If your Password is entered incorrectly three consecutive times, the user is “locked out” of the system.


Secure Data Transfer

The latest encryption technology helps ensure that another party cannot access your confidential account information. Encryption is a way to rewrite something in code, which can be decoded later with the right “key”. When you request information about your accounts, the information is sent across the web in an encrypted format to our processor. It then decodes your request and sends the requested information back to you in an encrypted format. When the information reaches you, it is decoded so that you and no one else can read it.


Router and Firewall

In addition to the above safeguards, sophisticated firewalls and an authentication process ensure that only authorized individuals are allowed to enter our system.


How you can protect your Internet Security

While Commercial Bank works to protect your banking privacy you will also play an important role in protecting your accounts. There are a number of steps you can take to ensure that your Commercial Bank Internet Banking account information is protected including:

  • Log out of Commercial Bank Internet Banking prior to visiting other Internet sites.
  • If you notice suspicious or unusual activity on your Commercial Bank accounts, call (620)421-1000 immediately.
