Invalid PIN

This error appears for 2 reasons on a PAX Terminal.
  1. The merchant is processing a debit transaction and the customer enters their PIN number incorrectly. This will result in a Host Response of Invalid PIN.
  2. The merchant attempts to process a debit transaction and the Terminal responds with Invalid PIN.
    1. Check if the terminal has correct Injection Keys/ Encryption
    2. If the terminal recently did a Firmware Update and it has not had one in several years the terminal may need to be re-encrypted.
