More and more banks offer ATM transaction to their customers.
A possible scenarion of such a careless withdrawal could be like that:
The customers can use a mobile app to preset how much money they want to withdraw from the ATM on future visits. Once they arrive at the ATM, they sign into the mobile banking app on their phone with their four-digit password.
On the phone, they select the cardless cash option, which will open the smartphone’s camera. Then, on the ATM screen, the customer touches the “card-less cash” button, which creates a QR code… Customers hold their smartphones over the QR code on the ATM screen, tap submit, and the ATM dispenses their cash.
This can be seen as an improvement of transaction security – no card no skimming.
