It’s our mission to save you time, stress and money. We want to introduce you to a new mobile product that does all three things: Arsenal CardKey.

CardKey works as its own app, separate from mobile banking, dedicated to letting you control how your debit and credit cards work. CardKey is more powerful and more customizable than the alerts and controls* feature we’ve provided for the last few years.

Check out all the cool things CardKey can do for you

Control where, when and how your cards work

You can set controls around things like purchase amounts, merchant types and locations. You can also receive notifications when transactions outside of those controls are attempted. Previously, with alerts and controls, you were only able to set up controls on a credit card. Now, you can set up the same security settings on both credit and debit cards.

For business members: Imagine being able to control where your corporate debit and credit cards are used by your staff. With CardKey, you can turn off transactions for unnecessary merchant types. For example, if an employee is traveling, you can allow transactions at gas stations, hotels and restaurants, but deny eCommerce and other types.

Lock and unlock your cards instantly from your mobile device

There’s nothing as stomach-sinking as losing your credit or debit card. With a simple tap of your screen, you can lock/unlock your cards if they’re lost or stolen. Locking/unlocking is also a good security measure for times you know you won’t be using your card (at work, asleep, etc.).

Use the button on the bottom-left of your card display to lock/unlock.

See, by card, every purchase you make

Budgeting is tough. CardKey lets you see every single transaction you make in real-time, giving you a glimpse into how often you use your card. You can even search by the stores you shop at the most to see just how much you’re actually spending at them.

This is where your transactions will appear.

And that’s not it…
