CardNav, The Ultimate Card Protection

Manage your ATM or Debit Card from anywhere

CardNav adds another level of security to Visa ATM and debit cards issued by SEG. This app allows you to decide how and when your debit card can be used, and alerting you when types of transactions you specify take place. You can even use CardNav to set personal spending limits that help you stay within your budget goals.

Some of the features include

  • Turn your debit card on or off in seconds.
  • Use GPS to restrict transactions to businesses within a designated area.
  • Limit your debit card use to specific merchants or purchases.
  • Receive real-time, in-app alerts that let you stop unauthorized purchases before they’re complete.
  • Receive alerts when you’re getting close to any personal spending limits you’ve set.

CardNav frequently asked questions

Will I need to authenticate the app each time I use it?
After the initial registration and two-factor authentication, you will only need to log in with your user ID and password or a four-to ten-digit passcode if the application’s session has timed out.
Can I manage someone else's card?
Yes, you can manage a card that is not yours. A great example of this would be to monitor a child's spending on their debit card.
Can the app be controlled from a desktop or laptop computer?
No, this is a mobile app and is controlled by a smartphone, Android tablet or iPad.
Does location functionality depend on phone signal?
An alert is triggered or a control is initiated by in-store transactions that occur outside of the area where your primary mobile device is located. The mobile device must have locations services (GPS) enabled with permission to use the current location. If your phone is turned off, without cellular service, or does not provide GPS location coordinates, it will use the last saved GPS location. However, if this situation occurs for more than eight hours, CardNav temporarily ignores the My Location policies. Transactions would not trigger alerts or control denials based on My Location preferences during this time; however an alert would be generated informing the cardholder that a transaction was conducted.
Will CardNav work outside the U.S.?
Yes. If your phone has an internet connection, the app will work.
How many cards can I set up?
There is no limit to the number of cards you can set up.
How does CardNav work with mobile security?
SEG's CardNav solution is particularly strong in terms of mobile security. The app mutually authenticates at both the app level and the cardholder level with the server. There is no sensitive information in the app. All sensitive information is tokenized. Communication is strictly through SSL with two-way authentication. The solution follows OWASP guidelines and meets or beats all accepted industry best practices.
Can transactions be conducted in foreign currencies?
Yes. Transaction amounts are displayed in issuer currency, but transactions may be initiated and authorized in any currency.
Are the in-app notifications via push, or do you have to be logged in?
Notifications are push notifications in app. You do not need to be logged in.
What if I have my card turned off and a recurring utility bill wants to charge my card?
When the card is off, most card transactions are denied by CardNav and alerts are generated for attempted transactions. However, auto-pay transactions and credits (deposits, returns and reversals) are exempt from this high-level control.
Can I use CardNav on multiple devices?
Yes, you can download and use the app on as many devices as you would like. If you are utilizing locational restrictions or alerts you will need to designate a primary device using the “settings” submenu.
