Introduction to the Acceptance Devices | PAX A77 Terminal
The PAX A77 is a portable Android SmartPOS (point-of-sale) payment terminal that is suitable for retail and hospitality environments. These are the terminal's features:
These card types or schemes are supported on the PAX terminal:
American Express
Diners/Discover
Mastercard
JCB
UPI
Visa
Supported Payment Card Input Methods on the PAX Terminal
The PAX terminal supports these payment card input methods:
EMV contact
Holding the card with the chip facing up, the customer inserts the card into the
card slot completely.
EMV contactless
The sensor area is located at the top of the terminal and is indicated by the
Tap (contactless) icon printed on the device. The customer holds and places the
card near the sensor area on the payment terminal.
Magnetic stripe
The device supports bi-directional (left-to-right or right-to-left) swiping of
the magnetic stripe on the back of the card. Holding the card with the magnetic
stripe facing down, the customer inserts the card into the magnetic card reader
slot and swipes the card through the slot at a steady speed.
Getting Started with the PAX A77 Terminal
This section describes how to get started with using the PAX A77 payment terminal.
Ordering PAX Terminal Equipment
This section describes how to order PAX terminal test and production equipment in the
European Union (EU), United Kingdom (UK), and United States (US). Due to regional
differences in related regulations and procedures, the ordering procedures described

for that Wi-Fi network. You must manually configure static access to your Wi-Fi network.
The procedure for adding a static network manually is similar to the procedure for
configuring a static network. The difference is that you must manually enter the network
name in the device settings instead of choosing the name from a list of available
(detectable) networks.

Configuring a PAX Terminal Cellular Connection Using a SIM Card
This section describes how to configure the PAX terminal cellular connection using a
SIM card.
If your Wi-Fi connection is out of range, the PAX terminal can use a cellular
connection to connect to the internet. Although using a cellular connection is slower
and possibly more expensive than using a Wi-Fi connection, it is an effective back-up
method.
A SIM card is required in order to configure a cellular connection for the payment
terminal. The SIM card provides access to 4G/3G networks for a cellular
connection.
IMPORTANT
A SIM card is not provided with the payment terminal, so you must purchase
it separately. Your service provider can recommend which SIM card to use with your
PAX terminal.
In order to help reduce data and operating costs, you can work with Customer Supporthttp://support.visaacceptance.com to remotely install software updates and
apps on your terminal using only a Wi-Fi connection.
Inserting the SIM Card into the PAX Terminal
Follow these steps to insert the SIM card into the PAX terminal:
Figure:
PAX A77 Terminal Back View Showing SIM Card Slot Locations
Turn off the power to the terminal.
On the back of the terminal, slide the battery cover latch to the right, then remove the compartment cover.
Remove the battery from the compartment.
Insert the SIM card into the lower-left corner of the compartment with the contacts facing down to match the contacts on the terminal. The diagram on the inside of the compartment shows where to insert the SIM card.
Replace the battery in the compartment.
Replace the compartment cover, then slide the cover to the left to close it.
Entering the SIM Card PIN into the PAX Terminal
Before you can enter the SIM card PIN into the PAX terminal, you must insert the SIM card
into the PAX terminal.
Follow these steps to enter the SIM card PIN into the PAX terminal:
Figure:
PAX Terminal Settings and SIM Cards Screens
Turn on the power to the terminal. The terminal prompts you to enter the PIN
for the SIM card that you installed.
Enter the PIN carefully because you are allowed only three attempts to
successfully enter the PIN. After the third attempt, you must enter a personal
unlocking key (PUK) before your mobile carrier blocks the SIM card.
When you enter the PIN successfully, the payment terminal detects the
SIM card. A notification appears on the screen.
To verify that the SIM card is recognized and enabled, tap the
Settings
icon on the terminal Home screen.
Enter your password, if prompted. The Settings screen appears.
In the Wireless & networks section, tap

Downloading and Installing Required Software and Encryption Keys
In order for the PAX terminal to operate correctly, it must have the required software
and encryption keys installed. The PAX terminal is configured to automatically download
and install software and encryption keys. This process is also referred to as
remote
software and key injection
. This automated activity provides merchants with a
secure way to perform injections at the point of sale.
These types of software and encryption keys are automatically downloaded and installed on
the terminal:
Operating system
The PAX terminal runs on a preinstalled Android operating system (OS) called
PayDroid. The PAX PayDroid OS is a specialized version of the Android OS
that was developed by PAX Technology specifically for its smart payment
devices. Although based on the standard Android OS, the PayDroid OS was
modified to provide a secure platform for payment applications and services.
It supports the installation of third-party apps, which must be approved by
PAX due to the sensitive nature of payment data.
Acceptance Devices app
This app downloads only on devices running the Acceptance Devices |
Semi-Integrated Solution in Semi-Integrated mode or Standalone mode. The
Acceptance Devices app enables communication between the PAX terminal and
the integrated POS system by using simple API requests in a local Wi-Fi
network or by using the cloud. You can also operate the Acceptance Devices
app in Standalone mode, which enables you to start transactions directly
from the PAX terminal. This mode does not require any integration to a POS
system.
Payment apps
BroadPOS Point-to-Point Encryption (P2PE) is a payment app developed by PAX
that manages card data encryption. It is an application interface that
enables your PAX terminal to acquire card information; support insert, tap,
swipe, and manual card payments; acquire the PIN; and encrypt the
transaction process. In order to read payment cards and process payments,
every PAX terminal must have BroadPOS P2PE installed. All PAX terminals that
are ordered through
Cybersource
and shipped by its
distribution partner automatically install BroadPOS.
Third-party POS app
This app downloads only on devices running the Acceptance Devices | PAX
All-in-One Solution. When performing an SDK/ All-in-One integration, a
third-party point-of-sale (POS) app that includes the SDK is installed and
run directly on the PAX device. If you are using a debug device, you can
install (or sideload) the app for development and testing by using a USB
connection to your laptop. Mac users must use Android File Transfer to
sideload apps. For more information about debug devices, see Ordering PAX Terminal Equipment.
Encryption keys
Every terminal running Acceptance Devices solutions will be equipped with a
set of encryption keys through remote key injection (RKI) after the terminal
connects to a Wi-Fi network for the first time. The Online PIN key is used
for encryption and real-time verification of PIN data. The Secure Reading
and Exchange of Data (SRED) key is applied in the encryption of card data
from the Point of Interaction (POI). This action ensures P2PE between the
terminal and gateway.
Installing Required Software and Encryption Keys on the PAX Terminal
Before the payment terminal can automatically perform remote software and key
injection, the device must be activated on the
Cybersource
platform. The
device must also be connected to the internet using a Wi-Fi network or Ethernet
connection.
These are the steps in the automated download and installation process for software
