These steps will allow your PAX device to accept card payments (tap, insert, or swipe) through the SharperMMS POS Register on a computer or tablet.
Note: The same setup is required for any device you want to connect to the register.
Step 1: Enable Device Payments
On your computer or tablet in SharperMMS:
Go to System Settings > Payment Methods

This setting is disabled by default
This setting must be enabled to allow device payments as well as to allow refunds for payments processed via the device.
Step 2: Add Your PAX Device
Go to Company Settings > Payment Device
Click Add New
Select Payment Processor: Payroc
Enter the following details:
API Key → Provided by Sharper Support
Terminal → Provided by Sharper Support
Device ID → Enter the serial number from the back of the PAX device
Step 3: Assign Device to POS Register
Navigate to POS > Register
Open your register settings
Under Payment Methods, select the PAX device you want to use
You can assign multiple registers to a single device if needed
Before Processing Payments (Important)
Ensure the Payroc app is open and connected on the device
If the Payroc app is not open or connected, payments may fail
You’re All Set!
Once configured, your PAX device will be ready to take card payments through the POS register.
⚠️ Using a PAX A920 Pro (On-Device POS)
If you are using a PAX A920 Pro to run Sharper directly on the device (dockside/tableside use), additional setup is required.
