Your pinpad has lost its encryption. This usually happens because of a power surge. Or from unplugging the pinpad, and then plugging it back in when the power is still on to the terminal. The pinpad must be encrypted with a code specific to your processor. You will need to contact your debit processor to have the pinpad re-encrypted.
