What Is Online Banking and How Does It Work?
Online banking is a service that lets you manage a bank account through a secure website, usually on a desktop or laptop browser. It's the right option when you want to check balances, move money, or pay bills without visiting a branch, and when your financial institution offers web-based access tied to an eligible account. Mobile banking is a related but separate channel — it runs through a phone or tablet app, while online banking runs in a browser. Many institutions, including Radius Credit Union, offer both, and the features often overlap.
What you can do with online banking
Once you're enrolled, most online banking platforms support a core set of tasks:
- Check balances and transaction history — see current and available balances, and review posted and pending transactions.
- Transfer funds — move money between your own accounts, and often to accounts you hold at the same institution.
- Pay bills — set up payees and schedule one-time or recurring payments.
- Deposit checks — many platforms let you submit a photo or scan of a check.
- Download statements — retrieve and save monthly or periodic statements as PDFs.
- Manage cards and settings — some platforms let you report a lost card, set alerts, or update contact details.
What's actually available depends on your institution and account type. A basic savings account may only support balance checks and transfers, while a full checking account usually unlocks bill pay and check deposit.
Online banking vs. mobile banking vs. branch banking
| Online banking | Mobile banking | Branch banking | |
|---|---|---|---|
| Access device | Web browser (desktop/laptop) | Phone or tablet app | In person |
| Typical strength | Larger screens, easier for detailed tasks like statements and payee setup | Convenient for quick checks and deposits on the go | Complex issues, cash, notary, and account opening |
| Availability | Usually 24/7, except during maintenance | Usually 24/7 | Limited to branch hours |
| Best for | Bill pay, statement review, transfers | Quick balance checks, mobile deposit | Problems that need a person or paperwork |
You don't have to pick one. Most people use online banking for planning and detailed tasks, mobile banking for quick actions, and a branch when something needs a signature or a conversation.
How to enroll and set up access
The exact steps vary by institution, but the general flow looks like this:
- Confirm eligibility. You typically need an existing account in good standing. Some institutions restrict certain account types from online access.
- Find the enrollment page. Look for a "Sign up," "Enroll," or "Register" link on your institution's official website. Type the address yourself rather than clicking a link in an email.
- Verify your identity. You'll usually enter your account number, Social Security number or member number, date of birth, and sometimes a one-time code sent to your phone or email.
- Create credentials. Choose a username and a strong, unique password. Don't reuse a password from another site.
- Set up two-factor authentication (2FA). If offered, enable it. This sends a code to your phone or uses an authenticator app when you log in from a new device.
- Log in and confirm your accounts. Check that all your accounts appear and that balances look right.
- Set preferences. Turn on alerts for large transactions or low balances, and add payees if you plan to use bill pay.
Expected result: you can log in, see your accounts, and complete at least a balance check and a transfer. If any step fails — for example, identity verification rejects your information — contact your institution directly rather than retrying repeatedly.
Security practices that matter
- Use a strong, unique password. A password manager makes this practical.
- Turn on two-factor authentication. It's the single biggest protection against someone using a stolen password.
- Recognize phishing. Banks rarely ask for your full password, PIN, or one-time code by email or text. When in doubt, log in through the official site or app instead of clicking a link.
- Check the URL. Confirm you're on the institution's real domain before entering credentials.
- Monitor regularly. Review transactions weekly so unauthorized activity gets caught early.
- Log out on shared devices. Don't let a browser save your session on a public or shared computer.
Requirements and limitations to expect
- Account eligibility. Online access is generally tied to holding an account; some account types may have limited features.
- Transaction cut-off times. Transfers and bill payments made after a daily cut-off may not process until the next business day. Bill payments to external payees can take several days to post.
- Deposit holds. Mobile or online check deposits may not be immediately available; funds can be held for a period before you can spend them.
- Maintenance windows. Platforms occasionally go offline for updates, usually during off-peak hours.
- Identity verification. If you can't verify your identity online, you may need to visit a branch or call to finish enrollment.
If a feature you need isn't available online — like opening a specific account or resolving a dispute — a branch visit or phone call is still the reliable path.
