Operating Your EFTPOS Terminal

Offline Transaction Processing
Offline transactions are those your terminal approves without contacting the card issuer. The
approved transactions are forwarded to the issuer at a later stage. Offline transactions are
allowed for a number of reasons outlined below.
Card Rules
Certain transactions are considered low risk and do not need to be authorised online.
Transactions in this category are known as off-host transactions. Below is a list of off-host
transaction responses:
Y1 = Offline approved
Z1 = Offline declined
Y3 = Unable to go online approved offline
Z3 = Unable to go online and declined offline
Electronic Fallback
If approved by Fiserv, your EFTPOS terminal can be configured for electronic fallback mode.
The 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 confirmation and will be approved with a response code of “08 Approved
with signature”.
Transactions above the floor limit will prompt the user to enter an authorisation number. You can
obtain an authorisation for EFB transactions by contacting the help desk at 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.
Electronic fallback is an optional feature. You may enable and disable this feature by contacting
Merchant Services at 1800-243-444.
