Automatic Installation of Software and Encryption Keys on the PAX Terminal
A PAX terminal must have the required software installed and encryption keys injected to
operate correctly. Terminals are configured to automatically download and install these
components through a secure process known as
remote software and key injection
.
This automated process enables merchants to perform injections securely at the point of
sale, without manual intervention or the need for specialized equipment.
These types of software and encryption keys are automatically downloaded and installed on
the terminal:
Operating system
PAX terminals operate on a preinstalled Android-based operating system
known as
PayDroid
. Developed by PAX Technology, PayDroid is a
customized version of the standard Android OS, specifically designed to
support secure payment applications and services.
Although it shares the core framework of the Android OS, PayDroid
includes modifications that enhance security and reliability for payment
processing. It supports the installation of third-party applications.
However, due to the sensitive nature of payment data, all apps must be
approved by PAX before installation on the device.
Acceptance Devices app
The Acceptance Devices app installs only on terminals running the
Acceptance Devices | PAX Acceptance Devices App in either
Semi-Integrated or Standalone mode.
In Semi-Integrated mode, the
app enables communication between the PAX terminal and the integrated
POS system by using simple API requests over a local Wi-Fi network or
through the cloud. In Standalone mode, the app enables transactions to
be initiated directly from the terminal without requiring integration
with a POS system.
Payment apps
To read payment card data and process payments, every PAX terminal must have
BroadPOS Point-to-Point Encryption (P2PE) installed. BroadPOS P2PE is a
payment app developed by PAX that manages card data encryption. It serves as
the interface that enables a PAX terminal to perform these functions:
Acquire card information
Support inserted, tapped, swiped, and keyed entry modes
Capture PINs
Encrypt the transaction process
All PAX terminals ordered through
Cybersource
and
shipped by its distribution partner automatically include BroadPOS P2PE as
part of the provisioning process.
Third-party POS app
This app installs only on devices running the Acceptance Devices | PAX
All-in-One Solution. When integrating with the SDK or PAX All-in-One, a
third-party POS app that includes the SDK is installed and run directly on
the PAX terminal. On 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 applications. For more
information about debug devices, see Ordering PAX Terminal Equipment.
Encryption keys
Every terminal running Acceptance Devices solutions is equipped with a set
of encryption keys through remote key injection, after the terminal connects
to a Wi-Fi network for the first time. The Online PIN key is responsible for
encrypting and verifying PIN data in real time. The Secure Reading and
Exchange of Data (SRED) key is used to encrypt card data captured at the
Point of Interaction (POI). This process ensures P2PE between the terminal
and the payment gateway.
Software Installation and Encryption Keys Injection on the PAX Terminal
Before a payment terminal can automatically perform remote software installation and
encryption key injection, it must first be activated on the
Cybersource
platform. To perform these automated processes, the terminal must be connected to the
internet using a Wi-Fi or Ethernet connection.
The PAX terminal initiates this automated process to install software and inject
encryption keys.
System connection:
The terminal establishes a secure link to the PAX
terminal management system (PAXSTORE) using a Wi-Fi or Ethernet
connection.
Download initiation:
The terminal automatically begins downloading all
required software packages and encryption keys.
Activity notification:
The terminal makes a brief audible signal to
indicate the start of the download process.
Progress display:
The terminal screen displays
real-time status messages about the components being downloaded. If the terminal
does not emit a sound or display download progress messages, open the PAXSTORE
app on the Home screen to verify that the terminal is connected to the PAX
terminal management system. You can also manually trigger downloads in the
PAXSTORE app.
Fix the
Accessory Update Required
Error on the PAX Terminal
The
Accessory Update Required
error appears on the PAX terminal when the
installed version of the Android SDK is incompatible with the BroadPOS P2PE version

If you are considering performing a factory reset to resolve an
issue, it is recommended that you explore other troubleshooting options first. A reset
erases all configurations, installed applications, and locally stored data, which might
not be necessary for resolving common issues.
