Step 2: Add extension to Shopify POS

After installation on Shopify admin, you will need to add the app extension on Shopify POS. This can be done in a few easy steps. From the Shopify POS homepage, click ‘Add Tile’. Select ‘App’ and then ‘MSA Checkout’ from the following pages. From here click ‘Add’ on the ‘MSA Checkout’ POS UI extension. This will add a new tile to your homepage.

Note: Your homepage may have several pages with many titles, so if you can’t see the extension on the first page, you may need to swipe to the next. Make sure to rearrange the titles to suit your store.

Step 3: Add terminal ID to settings

Click the extension tile and navigate to the ‘Settings’ tab. Enter the Station ID of the terminal you would like the current tablet to connect to (the Station ID can be found on the bottom side of your terminal or contact your provider). Click ‘Save’ and you’re ready to go.

EFTPOS in New Zealand

Shifting to Shopify POS and still want to accept EFTPOS?

If you’re a retail merchant in New Zealand who has recently moved or thinking of moving to Shopify POS, you may have noticed that Shopify does not natively support EFTPOS transactions nor Verifone or Windcave terminals.

But don’t worry – we have the solution!
