Auth 200 - Means there is either not enough money on the card your charging or there is some form of security restriction on the card itself.
Hold-Call (Voice Op) - Means call your bank processor, they need to verify the credit card information. Once completed they will give you a voice authorization number to enter in when you run the transaction. Also if your processing platform is "FDC (First Data Corp.)" your processor does not allow Voice Authorizations.
Invalid term ID - This error usually implies there is an error processing your Terminal ID. This can mean one of two things:
A. This is the most probable cause, the bank processor suspended or terminated your account.
B. Typo when the terminal ID was entered into the system upon creation of your account.
Mod 10 Check Card Failed - Means the first 10 digits of the card your entering cannot make a valid credit card.
