The PAX A920 is an integrated portable payment device that lets you process payments initiated via the Payabli Virtual Terminal or your own integrated software. The PAX A920 accepts payments via magnetic stripe, EMV chip, and NFC contactless technology. This guide walks through the steps to set up your new PAX device and register it with Payabli so you can start processing transactions.

Contact your Payabli solutions engineer to start the process of integrating with the PAX A920.

Prepare the device

When you receive your PAX A920 device, follow these instructions to unbox and get the device ready to register in Payabli.

Unbox the Device

The PAX A920 comes with a USB power cord and 3 rolls of receipt paper (one roll preinstalled).

Power the Device

Plug the device in to a power source. You can plug into a wall or a computer using the included USB power adapter.
Fully charge the device before turning it on.
When the device is charged, power it on by pressing and holding the small rectangle button on the right side of the device for 2 to 4 seconds.

Connect to WiFi

After the device boots up, it automatically launches the WSPLink app. You can’t use your own apps with the PAX device

Exit the WSPLink app by pressing the top left and bottom right corners of the screen at the same time.
Open the Settings app.
Toggle WiFi on, then press Wi-Fi. The device will detect nearby WiFi networks.
Select the network you want to connect to, enter password, and allow the device to connect.

The PAX A920 connects only to 2.4Ghz WiFi networks, and can’t connect to 5 GHz networks.

Press the circle icon at the bottom of the screen to go back to the home screen.

Let the Device Update

After the device connects to WiFi, it will cycle through updating the embedded software. This step can take up to 15 minutes, and the device may make some noises or alerts during this process.

Don’t turn off the device, open any apps or disconnect WiFi during the update process.

When the updates have finished, the screen will be fully white.

Open WSPLink

WSPLink is the app that you use to make transactions. Press the WSPLink icon to open the app.

The screen may be blank or all white. This is normal. The screen lights up when a payment is sent to it.

Register the Device in Payabli

Now, you must register the device in Payabli before you can accept payments.

Register the device

Now, you can register the device. Depending on your situation, you register the device via the device management UI of your integrated software, or using PayHub.

To register the device in PayHub:

From the PayHub for the merchant, click Settings.
On the next screen, click Devices.
Click Add Device.
In the Add Device modal:
- Enter a Device Description. This is the device nickname. Use something descriptive like “Front Desk POS”.
- Enter the Device ID. For the PAX A920, the Device ID is the serial number located on the back of the device. It’s the 10-digit number after the “S/N” on the barcode sticker.
Save when finished.
