Why do ATM PINs have 4 digits?
Earlier, customers had to stand in queues for hours in banks to withdraw money. But with the facility of ATM, it is easy to withdraw money. Now people go to any bank ATM machine near their home and withdraw money easily. But a four digit pin code is required to withdraw money from an ATM. After inserting the ATM card in the ATM machine, the withdrawal cannot be done without entering the four digit PIN code, so this four digit PIN code is very important. But have you ever wondered why the ATM pin code is only four digits, then let's find out…
We now withdraw money from ATM machines by entering a four-digit PIN code, but initially, withdrawals were made by entering a six-digit PIN code. Because a six digit pin code was considered better in terms of security than a four digit pin code. But often people did not remember the six digit pin code, thus facing many problems. After this it was decided to keep the ATM PIN code four digits.
Now very few banks use six digit pincode for ATM cards. Many countries around the world also have a six-digit PIN code for ATM cards. If there is a six digit PIN code instead of four then no one can remember another person's PIN quickly. This also greatly reduces the chances of pin hacking.
