VeriFone VX 820 Duet Installation Instructions

Electronic Ofine Vouchers (EOV) allow
you to process transactions ofine if your
terminal is unable to go online to authorise
transactions.
The terminal is permitted to go into EOV
mode for any of the following reasons:
• Telecommunication errors
• Our network unavailable
• Power outages
• System faults
• Failure to clear pending transactions
EOV is available on both magnetic swipe
and chip cards for debit and credit card
transactions.
EOV is not designed to function as
a secondary connectivity option. It is
intended as an emergency continuation of
processing capability when situations such
as a loss of network or connectivity occur.
Benets
EOV will lessen the impact of network
or communication outages offering you
continuity to processing payment.
Transactions can still be processed through
your terminal in a safe and secure manner
when EOV has been enabled, providing
you with extra reliability and peace of mind.
EOV makes manual ofine vouchers a thing
of the past and reduces the likelihood of
errors.
How EOV works
If a transaction fails twice, for one of the
reasons listed above, the terminal will
automatically go into EOV mode. Once in
EOV mode, rather than trying to go online
to authorise each transaction, the terminal
stores the transaction information until it
can go online.
The full card number is printed on the
merchant copy of the receipt, in case the
terminal faults or is unable to go online,
to upload the stored EOV transactions.
The card number on the customer copy is
truncated.
While in EOV mode the terminal will attempt
to go online every 10 minutes. Once it is
able to go online the terminal will upload the
stored EOV transactions to our network.
What you need to know
There are a number of limits / restrictions
applied when a terminal is in EOV mode.
These are as follows:
• The maximum dollar amount allowed
per EOV transaction is $300
• The maximum number of EOV
transactions allowed up until midnight
is 200
• The EOV duration period resets at
midnight each night
• The maximum dollar amount per
terminal while in EOV mode is $5,000
for credit and/or debit card transactions
• Only one EOV transaction per card, per
account, per EOV session is permitted
on each terminal
• Not all transaction types are permitted
in EOV mode. Transactions not
permitted are:
- Cash Advance
- Refund
• Not all card types are supported in
EOV mode; e.g:
