Get the Answers to Your Questions About Mobile Banking

Online banking solutions offered by credit unions make managing your finances easy and convenient. Although you can stop by a credit union branch any time for face-to-face assistance, most of your financial tasks can be completed remotely through a secure website. If you’re already taking advantage of the perks of online banking, why not take the next step of using mobile banking? Your credit union representative will be happy to help you get started.

Is mobile banking safe?

Although safety is a valid concern when it comes to mobile banking, the security of your money is a priority for your credit union. Because identity theft is a rapidly growing crime that can affect anyone, financial institutions have invested considerable resources into protecting the digital data of their customers. In fact, mobile banking can actually improve your financial security because you can get alerts when there is unusual activity on your account. This allows you to take action right away, regardless of where you are.

How can I protect my security online?

Although mobile banking is quite safe, it’s still smart to take a few extra steps to protect your sensitive information. One of the most important steps to take is to download the mobile banking app directly from your credit union, rather than using your smartphone’s Web browser to go to the website. It’s also best to use your cellphone carrier’s secure network or a trusted Wi-Fi hot spot, rather than public Wi-Fi. Always log out after each session and never click an option to save your password. You should also require a password for the phone itself.

What can I do with my mobile banking app?

This varies, depending on the financial institution you use, but in general, you can do anything with a mobile app that you can do with an online banking account. You can check your balance, receive alerts, and transfer funds.
