Card rules

not need to be authorised online. Transactions in
this category are known as off-host transactions.

Electronic fallback
If approved by First Data, your EFTPOS terminal
can be congured for electronic fallback mode.
The First Data EFTPOS terminal will enter electronic
fallback mode if there is a problem transmitting the
transaction to the card issuer. This could be due to
a communications error or due to the issuer being
unavailable.
These transactions are known as electronic fallback
(EFB) transactions.
All EFB transactions require signature conrmation
and will be approved with a response code of “08
Approved with signature”. Transactions above
the oor limit will prompt the user to enter an
authorisation number.
You can obtain an authorisation for EFB
transactions by contacting the helpdesk on
1800 243 444.
Please note that in EFB mode, the terminal may
prompt the customer to enter their PIN and
provide their signature. In all cases, please follow
the prompts on your terminal.
Ofine transaction processing
Ofine transactions are those your terminal approves without contacting the card issuer. The approved
transactions are forwarded to the issuer at a later stage. Ofine transactions are allowed for a number of
reasons, outline below.
