For your ATM debit card, you have a $4$-decimal-digit personal secret code. In the absence of any clue, a brute-force attack takes time-$'t'$ to crack the code on an ATM terminal. Therefore $'t'$ is the secure-time for a customer to report in ... personal secret code. Reduce the processing speed of the ATM terminals to the half of their current speed. None of the above provides any improvement.
