Credit Card Transaction Messages
If you see one of these codes on the credit card summary screen and the line is RED there is an issue with that particular card or transaction. This card CANNOT be used if you see any of these values. You must get a new card from the guest. The exception is a ‘c’ and this transaction will need to be processed by night audit via the Dollar on the Net site.
CC’s displayed in a red line, 1st character means:
n = missing name
e = bad expiry date
t = bad card type – we don’t accept this type
$ = token expired
d = transaction declined
c = check later (use EOD process)
x = transaction deleted
? = any other error
! = unprocessed/unposted transaction thru DOTN
