Why does BDO uses only 6 digits ATM PIN? Why not 8 or 10? And why not 3 only?
If you use 8 digits ATM PIN, it's very hard for you to memorize your PIN in that way. It could cause more problem to ATM accountholders that they will be blocked from accessing ATM (machines) because they forgot their lengthy 8-digit ATM PIN. Likewise, a 3-digit ATM PIN could also cause more unauthorized access of ATM card. If you steal an ATM card, you can easily guess the 3-digit ATM PIN.
A 6-digit ATM PIN is more secure than the 3-digit PIN. A 6-digit ATM PIN is also more convenient to memorize than the 8-digit PIN. The 6-digit PIN is the better way, a more stable.
