Avoid Banking While on Public Networks
Many mobile devices allow you to connect to different types of networks, including Wi-Fi networks. You might be tempted to check your balance or make some transfers while you grab a quick drink at a coffee shop. But before you log into your account, make sure you're not connected to the public network.
Public connections aren't very secure -- most places that offer a public Wi-Fi hotspot warn users not to share sensitive information over the network. If you need to access your account information, you may want to switch to another network. If you're using a smartphone or other cellular device, disabling the Wi-Fi and switching to a cellular network is a good solution. You never know who might be listening in over the public network.
