How to mask Pin Numbers when you type in ATM or in your Mobile screen login

                     

When you go to the ATMs or type pin numbers in mobile phones, use the second technique, just pretend you're typing other numbers besides the main numbers.

Instead of going in sequence in the password for e.g. 1234:

1 -> 2 -> 3 -> 4

Use a random sequence like this:

 1 -> 9 -> 2 -> 3 -> 7 -> 4

to confuse those who're watching what you type.
