Before you start, have ready
- A Windows 10 or 11 computer at your counter
- Your merchant portal open on any device
Step 1: Download and install
On the counter computer, go to the Download page and press "Download for Windows".
Open the file you downloaded and follow the installer. If Windows shows "Windows protected your PC", press "More info" and then "Run anyway". This message appears for new apps that are not yet widely downloaded.
Tip: You only install once. MuffinPOS tells you when a newer version is ready.
Step 2: Get your activation code
In the merchant portal, open "POS setup" in the left menu.
Give the till a name (like "Front counter") and press "Generate new activation code". You will see three things: Tenant ID, Location ID and a 6-digit code. Each has a "Copy" button.
Tip: Each code works once. If something goes wrong, generate a new code instead of retyping the old one.
