Nowadays, one such claim is being made on social media, in which it is being told that after withdrawing money from the ATM, pressing the 'Cancel' button once or twice cannot lead to PIN theft.

A viral social media post has been making the rounds, claiming that pressing the 'cancel' button twice before inserting an ATM card can safeguard you against PIN theft.
