Old Second National Bank’s O2 Online Banking system utilizes a comprehensive security strategy designed to protect your accounts and transactions conducted over the Internet. In addition to our login security, we use the SSL (secure socket layer) encryption technology for everything you do in the O2 Online Banking system. This technology is automatically activated by your browser when it attempts to connect to our system. Whenever SSL is securing your communications, the browser will typically indicate the "secure session" by changing the appearance of a small padlock icon at the bottom of the screen from open to locked. When locked, your communications are scrambled from your browser to our servers at all times to help prevent an unauthorized party from reading the information as it is carried over the Internet. The Online Banking service can be accessed using the most current and prior major release of the following browsers:

  • Microsoft Internet Explorer (IE)
  • Firefox
  • Safari (v. 6 only)
  • Google Chrome

During your use of the O2 Online Banking system, we will pass a "cookie" to your browser for identifying you during the session. We do not (and cannot) use our cookies to obtain new information about you or to read information stored on your hard drive. A "cookie" is a way for web sites to recognize whether you have visited the site before. It is a piece of data given to a browser by a web server, so that the browser will hand it back to the server on subsequent visits. When you log into the system, this cookie enables us to process multiple transactions during the session without you having to provide your O2 Online Banking ID and password for each individual transaction. When you log off, or after ten minutes of inactivity, the cookie is no longer accepted and must be renewed by re-entering your password. A new cookie is used for each session. That way, no one can use the cookie to access your account. We are not responsible for the security of the information stored on your personal computer. We strongly encourage our customers to clear the cache on their computers immediately after conducting financial transactions over the internet. Please use your browser help function for instructions on doing so.

In addition to the security measures described above, there may be other security notices posted on the website regarding security issues. It is your responsibility to read all applicable notices. One of the main security features regarding the use of the O2 Online Banking system is the ID and password. It is important that you keep your password secret. We will not be liable for any losses resulting from you permitting other persons to use your O2 Online Banking ID and password to access the system or failing to clear the cache from your browser session. If you have more questions about our security systems for conducting transactions safely over the Internet, please contact us.


We recommend your browser settings be set so your browser will check for new versions of Temporary Internet files every time you start your browser.


The O2 Online Banking service requires that the customer complete the initial registration process. This involves completion of the enrollment form that will identify you to Old Second National Bank and provide certain information that we will need to enable the service. We will verify the information you submit for accuracy and authorizations. In about two business days, you will be notified when your account will be activated.


At the time you request the service, we will provide you with a unique "Online Banking ID" and "Online Banking Password" that will be used to gain access to the system. Prior to activation, we will verify your identity and authorization to information associated with the accounts that you requested through the service. You must change your password on your first successful login.

To help prevent unauthorized access and ensure the security of your accounts, we will end your online session if we have detected no activity for 10 minutes. This helps protect you in the event that you accidentally leave your computer unattended after you've logged on.

Because your password is used to access your accounts and we are entitled to act on instructions received under your password, you should treat it as you would any other sensitive personal data. You should carefully select a password that is hard to guess. Keep your password safe. Memorize your password and never tell it to anyone.

Our online security feature allows us to identify the computer(s) you normally use to log on. To assist in preventing someone from accessing your accounts from an unknown computer, we may occasionally need you to verify your identity when you login. This is done by answering security questions that you have already established in the Options section of O2 Online Banking. We will never ask you to e-mail your personally identifiable information such as your social security number or account number.

LOGIN SECURITY (Cash Management Users)
As a business customer, you can establish separate logins for each employee you designate to have access to your Online Banking accounts. The login consists of a unique Cash Management ID and Cash Management password and is in addition to the Online Banking ID and password. This provides you with control over specific levels of access for individual employees. If you set up one or more additional employees for access, you become the administrator and agree to be responsible for establishing and maintaining IDs and passwords.

We also offer a Single Sign On feature that would convert the four credentials, Cash Management ID, Cash Management Password, Online Banking ID, Online Banking Password, into one Single Sign On ID and one Single Sign On Password.

You may request to access any account on which you are a signer or owner. If you desire services that allow you to initiate payments or transfers from the account, you will need the required withdrawal authority over the account to be able to complete the transaction. By using the service, you agree to maintain one or more accounts with us and to keep sufficient balances in your account to cover any transactions and fees that are ultimately approved by or related to the system. We will not be obligated to act on any withdrawal instructions from you if you do not have sufficient funds, including overdraft lines of credit, available in the account you designate. If the accounts added to the service are jointly held or have multiple signers, you agree that access to the information and all transactions initiated by the use of your ID and password are authorized unless we have been notified to cancel the service. Once an account is added, regardless of which of the primary or secondary contacts is the owner, responsibility must be taken by all account holders for all transfers, withdrawals, bill payments, etc. Minor account owners will require the approval of the primary owner prior to debit transfer access being approved.

The O2 Online Banking and O2 Bill Payment service is free for all customers. Business customers who utilize treasury services may incur additional fees.

Your O2 Online Banking may be canceled at any time by us in whole or in part without prior notice to you due to insufficient funds in one of your accounts or other circumstances that may create an unanticipated liability to us. You will remain responsible for all transactions approved by the system prior to the cancellation, and for any other fees associated with the service. After cancellation, service may be reinstated once sufficient funds are available in your accounts to cover any fees and other pending transfers or debits. In order to reinstate the O2 Online Banking service, you must reapply for the service.

You may use O2 Online Banking to check the balance of your accounts and to transfer funds among your accounts. According to Federal regulations, you may not make more than six (6) pre-authorized or automatic transfers or bill payments from your Money Market Deposit Account or Savings Account during a given monthly statement period. There are no limits to the number of transfers or bill payments from your Checking Accounts. Currently, the bill payment service is limited only to Checking Accounts. Balances shown in your accounts may include deposits subject to verification by us. The balance may also differ from your records due to deposits in progress, outstanding checks or other withdrawals, payments or charges. A transfer request may not result in immediate availability because of the time required to process the request. If you have further questions, contact us. The balances are updated in "real- time" and the system will display the most current "as of" date on the "accounts" summary page. Situations may occur that cause a delay in an update of your balances. The system will use the most current balance available at the time of a transaction on which to base our approval. Any information you receive from us through O2 Online Banking is believed to be reliable. However, it can only be provided on a best efforts basis for your convenience and is not warranted or guaranteed. We are not liable for any deficiencies in the accuracy, completeness, availability, or timeliness of such information or for any investment or other decision made using this information.


You may use O2 Online Banking to receive Account Alerts based on specific criteria that you enter in the Options, Alerts section.  You can choose to receive your Alert notification upon signing into Online Banking, via Email or Text Message.  Providing your mobile phone number and carrier information for text alerts indicates your agreement to our sending text messages to you through your wireless carrier.  We do not charge for the service, but you are responsible for all charges and fees associated with text messaging imposed by your wireless service provider. 

The system includes several options that provide a means to securely forward your stop payment to us for processing. Generally, requests received from the system will be processed within one business day using procedures that would handle similar requests received by mail or fax. If urgent action is required, we recommend that you contact us directly by telephone or in person. Additional terms of acceptance or disclosures may apply on the Stop Payment service and these terms will be disclosed at the time that you complete the request. The Stop Payment feature is designed to submit a request to stop payment on checks you have written. We do not guarantee the ability to successfully stop a payment within the first 24 hours from the time of the request due to timing issues. The stop payment order is effective for only six months, unless it is renewed in writing. Once a stop payment order expires, the Bank may pay the item. There may be additional fees associated with some of these services. This service is not available to cancel the payments scheduled through the bill payment service. If you have a problem or need to cancel a bill payment, you will need to contact us.

It is easy to pay bills online. Simply set up your Payees by choosing from our large database of electronic vendors that already exist. If your vendor is not listed in our electronic database you may enter the Payee as a check payment. We should be able to process payments to any payee that has a U.S. Postal address.

The daily limit for the total dollars of payments approved is governed by the system’s available balance in the checking account selected for making the payment. You can withdraw up to the system’s available balance as long as your account shows sufficient funds to cover your payments. Bill payments that you initiate are drawn on your checking account(s) like any other check that you write. NSF bill payments will be treated like any other NSF item presented to the bank for payment. Repeated occurrences of NSF bill payments may result in suspension or cancellation of bill payment privileges.

Please note the following when scheduling Bill Payments through O2 Online Banking:

  • Payments entered on our system after our cut-off time, 12:00 Noon CT each business day, will not be processed until the next Business Day.
  • Payments do not get processed on holidays or weekends. If a scheduled payment falls on a holiday or weekend, it will be processed on the Friday before the weekend, or the last business day before the holiday.
  • If we have to send a paper check in the U.S. Postal System, we typically suggest a Pay On Date that’s at least ten (10) full business days prior to the date that you would like the payee to receive the payment for processing at their address. We are not responsible for postal delays.
  • If the payee accepts the payment electronically, we generally suggest a Pay On Date that’s at least three to four (3-4) full business days prior to the date you would like the payee to receive the payment.
  • Our system assumes the payee/vendor will promptly process the payment on the business day it is received. Any delays caused by the payee/vendor would result in additional delay before the payment would show on their records. We are not responsible for processing delays by the payee.

The service is free for all O2 Online Banking customers.

We do not have any duty to monitor payments made through the Bill Payment service. If you are a business and an authorized representative of yours uses your Bill Payment service to pay bills which are not yours, you assume the entire risk of loss and indemnify and hold us, our directors, officers, employees, and agents harmless from all loss, liability, claims, demands, judgments, and expenses arising out of or in any way connected with such use.

It is our responsibility to process all bill payments properly initiated through the O2 Online Banking system in accordance with this Agreement. We will be liable for damages, as defined in this Agreement, where the system caused a payment delay or failed to process a payment. We are not responsible for processing delays by the payee.

We will not be liable if any of the following occurs:

  • Funds are not showing on the system’s available balance in your account that is selected to pay for the bill or transfer at the time of transaction.
  • Funds are subject to legal process or other encumbrances restricting the payment or transfer.
  • You had knowledge of or questions about the possible malfunction of the system when you initiated the transaction.
  • Any information provided by you about the Payee is incorrect.
  • There are any delays in the handling or processing of the payment by the Payees or merchants through no fault of O2 Online Banking or our service providers.
  • Natural disasters (for example, fire, flood, tornado) or other uncontrollable circumstances (for example, mail delays, power failures, Internet or electronic funds systems failures, strikes, acts of war or terrorism) prevent proper completion and delivery of transactions.
  • Other applicable laws and/or regulations exempt us from liability.
  • It can be shown that you were attempting to defraud us.
  • It can be shown that the delay was caused by the U.S. Postal Office.

In no event shall the Bank be liable for any direct, consequential, incidental, special or indirect losses or other damages, which you (the “Customer”) may incur or suffer as a result of fraudulent activity to your account(s), identity theft of any sort, or any damage to your computer or telephone service resulting from your use of the Internet to perform online banking, other financial transactions, or other activities as a result of malicious activity to your computer or other technology that is not part of, and under the direct control of, Old Second National Bank.

We will reimburse you up to $50 per payment for any late payment fees or penalties you are charged as a result of O2 Online Banking failing to deliver a payment to the Payee/Vendor or not receiving a payment by the Due Date if all of the following apply:

  • You scheduled the payment before the cut-off time on a transaction date at least ten (10) Business Days prior to the Due Date.
  • Information provided to us about the Payee (name, address, account number, and amount) was correct and complete.
  • Your account contained sufficient available funds to complete the payment or transaction on the transaction date.
  • The Payee was a Business Payee that charges late charges or penalties.
  • Late payment fees or penalties were assessed by the Payee, due to the delay of this payment.
  • You received no prior notice from the Payee/Vendor that there was a problem with processing payments from our system.
  • You received no notice within the ten business day period that would have allowed you to alert us of a problem where we could have taken corrective action to remedy the situation prior to the tenth day.


Notify us immediately if your O2 Online Banking ID and password have been compromised, lost, stolen or used without your authorization. Failure to notify us immediately could result in the loss of all money accessible by the password. Telephoning us at the number listed below in the Errors and Questions section is the best way of limiting your possible loss. You could lose all the money in your account (plus your maximum overdraft line of credit, if you have one). If we are notified within two (2) business days after you discover that your O2 Online Banking ID and password has been compromised, lost or stolen, you can lose no more than $50 if someone used it without your permission. If you do not notify us within two (2) business days, and we can prove we could have prevented someone from using the O2 Online Banking ID and password without your permission, you could lose as much as $500. If your statement shows unauthorized transfers, notify us within 60 days after the statement is mailed to you. After 60 days, if we can prove that we could have stopped someone from taking the money if we had been told, you may not get back any money from us. If a good reason, (such as a long trip or hospital stay) kept you from telling us, we may extend the time periods to a reasonable time. This section applies only to electronic fund transfers that debit or credit your checking, savings, or other asset accounts and are subject to the Consumer Financial Protection Bureau’s Regulation E. We may, when applicable, rely on any exceptions to the provisions in this section that are contained in Regulation E.
