How does that work?
The CBA app has a "Withdraw Cardless Cash" option of the main menu. Logging into the app requires a fingerprint on my phone.
Once you have selected the account and amount the app will generate an 8 digit code that is valid at any CBA ATM for 30 minutes. It will also SMS you a 4 number PIN that is needed to complete the transaction.
Voila! No card.
Each bank has their own app and simple process but roughly, it's the same.
