Getting Started
Unpacking the ViVOpay 8850
The ViVOpay 8850 requires a data cable and apower supply if thedata cable isnot supplying power.
Data cable and power supply are not included with the ViVOpay 8850 and should be purchased
separately from ViVOtech. Verify that you have all the required components for the installation.
You may also need the following:
• Additional SAM card
• Four M3 screws
If you want to secure the reader to a surface you need four M3 screws of the appropriate length
(not supplied).
• Contactless test card (ViVOcard Contactless Test Card P/N 241-0015-03)
• Magnetic stripe test card
• Wedge bracket kit (540-0006-00)
The ViVOtech data cables and power supply are specifically designed to meet FCC requirements. If
you are using other cables or power supply, you must install ferrites available from ViVOtech. For
your free ferrite core kit with installation instructions, please contact ViVOtech support.

Chapter 2
Installing the ViVOpay 8850
Overview
Before you connect and mount the ViVOpay 8850, you should plan the installation to conform to PCI
2.1 requirements andminimize radio frequency interference. Once you have determined the location
and mounting of the ViVOpay 8850, you can connect it to power and the POS terminal. Finally, you
should test the ViVOpay 8850 to make sure the installation is successful.
Site Planning
Two environmental considerations affect how you install the ViVOpay 8850. PCI certification has
specific restrictions on how the reader is positioned to prevent PIN theft. You should also consider
objects and devices near the reader that may affect the performance of the contactless radio
frequency antenna.
PCI PED Compliance
The ViVOpay 8850 is a PCI 2.1 certified PIN/Debit payment device. PCI 2.1 certification requires that
sufficient protection be provided to ensure that entering a PIN number CANNOT be viewed by a third
party (such as another customer standing nearby, the cashier, or a security camera).
The ViVOpay 8850 has design elements, such as a recessed keypad, that meet some of these
requirements. However, to fully implement PCI 2.1 make sure you consider the following.
1. The ViVOpay 8850 must be in a location that will NOT force a customer to enter a PIN that
can be viewed by a third party (for example, a customer must tilt or rotate the device for
better accessibility due to objects blocking a card swipe).
2. If the ViVOpay 8850 is elevated on a mounting stand, shielding must be provided on the
mount to prevent a PIN being viewed by a third party.
3. If the ViVOpay 8850 is mounted on a counter top, additional shielding (which can include
other devices such as a cash register as long as conditions in (1) above is met) must be
provided to ensure that the PIN cannot be viewed by a third party (including cashier and
security camera).
Verifying PCI Compliance
Before completing the installation, you must verify the ViVOpay 8850 is positioned so that the PIN
entry is not visible to other customers, the cashier behind the counter, or video surveillance cameras.
If PIN entry is visible, the ViVOpay 8850 must be repositioned or shielding added until PIN entry
cannot be observed.
These tests usually require at least two people—one to simulate entering the PIN while the other
attempts to view the keypad.
WARNING: PCI requires that the device be mounted so that the PIN entry cannot be
observed by a third party (such as another customer standing in line, the cashier at the
counter, or a security camera mounted in the ceiling to observe the cash register area). If
the PIN entry can be observed, the store owner may be responsible for any losses
incurred by the customer if it can be determined that the customer’s PIN was stolen at
this location.

ViVOpay 8850 User Guide 4
Installing the ViVOpay 8850
Can Another Customer View the PIN?
While one person stands at the ViVOpay 8850 with their hand positioned to enter the PIN, the other
tester should try to observe the keypad from behind and beside the first person.
Can the Cashier View the PIN?
While one person stands at the ViVOpay 8850 with their hand positioned to enter the PIN, the other
tester should stand behind the counterand try to observe the PIN keypad. The second tester should
move around a little to see if there is a position where they can observe PIN entry.
Can the Video Camera View the PIN?
While one person stands at the ViVOpay 8850 with their hand positioned to enter the PIN, the other
tester should observe what is being recorded by any video camerawith a view of the ViVOpay 8850.
This may require playing back a recording to see if PIN entry is visible. If the video camera is
moveable,thesecondperson shouldmovethe videocameratodetermine ifthereisapositionwhere
PIN entry can be observed.
Retesting Requirements
If PIN entry on the ViVOpay 8850 is observable in any of the above tests, you must reposition the
ViVOpay 8850 and completely retest all locations to verify that PIN entry is not visible. Consider
placing a display to block observation from that position.
Repositioning the ViVOpay 8850 to block observance of PIN entry at one location may expose PIN
entry to observation at another location. PCI requires that you reposition the ViVOpay 8850 and
retest until PIN entry is secure from observation.
Radio Frequency Interference
To perform contactless transactions, the ViVOpay 8850 uses a radio frequency antenna. The range
(reading distance) and performance of the reader can be affected by other radio frequency emitters
and proximity to metal.
For best performance, adhere to the following guidelines:
• Do not position the ViVOpay 8850 closer than 1 foot (30 cm) to ViVOpay 8850s or other
RF-emitting devices. Some environments may require greater distances.
• Avoid placing the ViVOpay 8850 on or near large metal objects.
• Do not position the ViVOpay 8850 near radio transmitters.

POS application.
If the unit fails to power up, try reseating the power connector (or change to a different power outlet).
If the unit still fails to power up, try replacing the power supply. If the unit still fails to power up, and
the power supply is definitely good, contact your local support representative. For more
troubleshooting information, see “Troubleshooting” on page 13.

Testing the Installation
After you have completed the installation and have checked for PCI 2.1 conformance, run the
Onboard Diagnostic program as described in “Onboard Diagnostics” on page 14. Then check that
the ViVOpay 8850 and the POS are communicating correctly by performing a sample transaction.
The following test assumes that the host POS is already programmed to communicate with the
ViVOpay 8850.
Transaction Test
The exact wording that appears on the ViVOpay 8850 depends on the POS application.
To test a transaction
1. Ring up a transaction on the POS. The ViVOpay 8850 may show Welcome or similar
wording.
2. Present a card/fob/phone in close proximity to the reader or swipe a magnetic stripe card.
3. A single beep and LED flash indicates that the card has been validated. The ViVOpay
8850 may display Processing or similar wording while the transaction is being
processed.
4. If the POS software requires a PIN entry, you will see Please enter PIN. Use the keypad
to enter the PIN.
5. If the POS application requires a signature, you will see Please sign below. Use the
stylus to enter your signature on the touch screen.
