4.13.2 Command Description

User gets promoted from the LCD for entering account password (PIN). After the PIN is
entered and the confirm key is pressed, the PINPAD will use the Card Number data received
from main host to generate PIN Block according to ANSI X9.8 Standard, and then encrypt
the PIN Block using PIN encryption Key.
When entering account password, user cannot cannel that operation; only main host can send
command to cancel PIN Entry.
For protecting against exhaustion PIN attack, the number of PIN Entry attempts is limited in
a period of time. Only 110 times of PIN Entry is allowed in 1 hour.
