Your Google Pay transactions are protected through:

• Android device security settings, like a PIN or password.
• SSL technology which encrypts your payment information
• Privacy measures to ensure your plastic card details are not shown in the app or shared with the merchant
• Notifications about where your transaction occurred along with the merchant’s name and amount of payment or refund.

In addition, Suncorp monitors your transaction history 24/7, to identify any unusual activity. You can contact Google directly about your device’s security features.
