Limit use to where you are.

Frequently misplacing your card? Traveling out of town? Keep your card active only when it’s in the same area as you. Simply define a region on a map or require your card and smartphone to be within the same vicinity. When you’re outside the specified region or your phone isn’t nearby, your card will automatically shut off, deterring potential fraudsters.

Caution: It's not called Cardpower for nothing!

The controls and settings in CardPower are designed to prevent others from using your card without your authorization, but that same power could prevent you from using your card if you're not careful! We recommend that you start by turning on alerts, so that you'll know immediately whenever your card is used – and where, and for how much. Then, one at a time, try setting the various controls and preferences until you find what works best for you. And if your card ever doesn't work when you think it should, turn off all controls and try again!

Frequently Asked Questions

Yes, recurring transactions that have already been set prior to turning the card off will continue to go through.
For Apple users, press the icon that has three stacked lines to reach the menu.

For Android users, here are three most common methods depending on device.
  • Press the dedicated menu button on your phone. This will pull up the CardPower app menu while you are logged in to the app.
  • Press the icon that has 3 stacked dots or stacked lines to reach the menu.
  • For devices that don't have either option above, hold down the recent apps button (lower left corner, next to the home screen). This will open the menu.
In some cases, the merchant may process all of their card transactions in a central processing center which could be in a different city, state, and/or ZIP code. Since the city, state, and/or ZIP code shows a location outside the area where your phone is located, it will decline when the My Location Control Preference is turned on. This is common with purchases made at vending machines or kiosks where the central processing is often performed in a different location than where the terminal is physically located. If you click on the transaction summary in CardPower, the city and state where the processing is taking place is located under the merchant's name.
CardPower allows you to control your card and set rules for where it cannot be used. However, even if a transaction is consistent with the usage policies that you have set, it may be declined for other reasons – for example the transaction triggered fraud rules or you do not have sufficient funds, etc. A transaction that fails your control rules will be declined, but a transaction that passes your control rules is still not always guaranteed to be approved.
Our fraud monitoring service stopped the transaction from posting on the account when it detected the transaction may have been fraudulent. Since the transaction did not carry all the way through to our processing system, it did not trigger a CardPower alert.
A "Server Unreachable" error means that the CardPower application could not connect to the CardPower server that communicates with Arizona Federal. Please tap on the bar again – sometimes the server is unreachable when your network connectivity is weak or intermittent, and retrying the connection by tapping on the "Server Unreachable" message connects the application to the server. If the problem persists, you may have to stop the application and restart it. If the server is down for maintenance, the problem may persist and you may have to try again later. If this consistently occurs during regular business hours, please contact Arizona Federal at (602) 683-1768.
There are times when the card network is unable to connect to our processing system due to connectivity issues, transactional volume, or maintenance periods. This is not frequent, but happens from time to time. When this occurs, Control Preferences will not work and purchases can be approved. If these are unauthorized transactions, please remember that you have Zero Liability Coverage on any unauthorized or fraudulent transactions on your account. Please report any unauthorized or fraudulent transaction to the credit union by filling out a fraud dispute form located under Additional Services within online banking. However, you are responsible for any legitimate purchases made during these times. It is a good practice to avoid "testing" the capabilities of the app because you are responsible for any legitimate purchases.
