Declined Transactions
The customer’s card, card issuer or the acquirer
can decline to
authorise any transaction.
A declined response from the acquirer’s host system will display a
message on your terminal in place of the usual
AUTH CODE: xxxxx
message. This can be, for example,
DECLINED
,
NOT AUTHORISED
, or
RETAIN CARD
. This message will be displayed on the screen for up to 60
seconds, or until the
enter
key is pressed.
A declined receipt will be printed which clearly indicates that the
transaction has not been authorised. It will also show the message from
the acquirer.
Transactions with an inserted Chip card may be declined by the card
without the terminal contacting the acquirer’s host system. You should
advise the customer to contact their card issuer and request another
means of payment.
If your terminal is unable to contact the acquirer for a transaction with an
inserted Chip card, the transaction maybe declined by the card with the
message
COMMS FAILURE DECLINED
.
If the
COMMS FAILURE DECLINED
message is displayed there
may be a problem with your telephone or LAN connection. This
will be indicated by the diagnostic (
DIAG
) codes printed on the
receipt. Refer to the section entitled
Diagnostic Codes
for more
details.
If you are prompted to retain the customer card you should
follow the standard procedures as laid down by your acquirer.
