Important information you need to know.
As a valued customer on the Paymark network, we wanted to make sure you have all the information you need relating to your
EFTPOS terminal. This communication covers Electronic Offline Vouchers (EOV), terminal security and fallback (when a chip card is
not working as it should). Please take the time to read the following information, and share it with your staff. You can also
find extra information on these topics on the Paymark website www.paymark.co.nz
Electronic Offline Vouchers (EOV)
What is EOV?
EOV comes into effect when connection with the Paymark network has been lost (such as a telecommunications issue). When an
EFTPOS terminal is in EOV mode transactions are stored in the terminal memory and are processed once connection to the
Paymark network has been restored.
How do I know the terminal has switched to EOV mode?
The terminal will display the message EFTPOS OFFLINE and will ask PROCESS TRANSACTION OFFLINE Y/N? to which you will
need to make a selection. Each receipt will have AUTH xxxx printed on it (below the card type).
What do I need to do?
Transactions will process as normal (i.e. you swipe or insert the card and proceed normally), however you will need to check the
card type to ensure it is a valid type that you would normally accept. You must also ensure that the card has not expired, and have
the cardholder sign the receipt as they will not be able to enter their PIN - even for EFTPOS transactions.
Important stuff I need to remember
• First check the terminal’s cables and phone line to ensure they have not caused the loss of connection with the Paymark
network.
• Try a manual logon.
• Transactions over $300 cannot be processed in EOV mode. Contact the Authorisation Centre and process these transactions
on a manual voucher.
• Refunds and cash out transactions cannot be processed in EOV mode.
• EOV transactions must be uploaded once connection to the Paymark network has been restored, do not leave them stored
in your terminal’s memory. Do not make any changes to your terminal until the stored transactions have been uploaded - if the
terminal ceases to operate or the software is replaced before the upload process is completed, you are at risk of losing your
stored transactions.

Terminal Security
It is vital that you do everything in your power to secure your customers’ payments and protect their personal information, thus
reducing the likelihood of credit and debit card fraud. We’ve come up with some best practice examples which we strongly suggest
you consider:
•
•
•
•
Always ensure that your terminals are secure and under supervision during operating hours. This includes any spare or
replacement terminals you may have.
Ensure that only authorised employees have access to your terminals and that they are fully trained on their use.
Never allow your terminal to be maintained, swapped or removed without advance notice from your terminal provider. Be
aware of unannounced service visits, check their credentials.
Inspect your terminals on a regular basis - check there are no additional cables running from your terminals and that the casing
has not been tampered with.

Fallback - Chip card not working
Cards with chips embedded in them should always be processed by “dipping” (inserting) the card into the terminal.
There are however, occasions where the chip cannot be correctly read by the terminal, resulting in the terminal prompting for the
card to be swiped. This is known as a fallback transaction and may be a caused by a faulty chip card or a faulty terminal.
The chip card must only be swiped if the transaction is unable to be processed via the chip. Merchants who force a transaction into
fallback increase the risk of fraudulent activity.
