Cash App Card Transaction Security
Customer security is one of our top priorities. If Cash App notices potentially unauthorized activity on your account, we may decline Cash App Card transactions for your protection. Depending on the transaction, we may send you a notification asking you to confirm whether you recognize the declined transaction within your app.
To do so:
Tap the Activity tab in the bottom right corner of your Cash App home screen
Locate the declined transaction pending review
Confirm if you do/do not recognize the transaction
This information helps us better protect your account from unauthorized transactions in the future. If no action is taken after receiving a notification, future transactions made at the same merchant will likely decline again.
