Quick answer: Finish or hold any open order. On the POS, open Nomni Store, tap the Nomni POS app for your device, then Install latest and Install on this device. Approve it from your phone, then open the download and tap Update. Steps are below.
Nomni POS for Android 2.3.26 lets you leave chosen categories out of a public holiday or other general surcharge, adds a Select Card Type step to card payments, and fixes multi-day surcharges, member QR scans and price triggers on products with variants.
What changed
Leave categories out of a holiday surcharge. If a general surcharge (for example a public holiday surcharge) has Exclude Category set in Nomni Console, the POS now leaves those items out of the surcharge. A product that sits in more than one category is left out if any of its categories is excluded. If every item on the order is excluded, no surcharge is added.
New Select Card Type step. When you pay by card, the POS now asks which card the customer is using, the same way Nomni POS on iPad does. The card you pick decides which card surcharge applies. It doesn't change which terminal or payment provider is used.
Surcharges set for several days now apply on all of them. A surcharge set for, say, Saturday and Sunday used to apply only on the first day picked. It now applies on every day you selected.
Member QR scans no longer show a false error. Some scanners read one QR code twice, which showed "Please refresh your member QR code and scan again" even though the member was added. The POS now ignores the repeat scan.
Price triggers can include variant prices. When a price trigger is set in Nomni Console to include variant prices, the discount is now worked out on the product price plus the price of the chosen variant, including on split payments.
How to update
Finish or hold any open order.
On the POS, open Nomni Store: the Nomni Store app, or go to nomni-store.web.app in the browser.
Tap the Nomni POS app for your device: Nomni POS (NON-Sunmi) (iMin), Nomni POS (Sunmi), or Nomni POS T-series (NON-Sunmi), Nomni POS N-series (NON-Sunmi) or Nomni POS N-Series (Sunmi) if your POS has a built-in Tyro or Adyen reader. Then tap Install latest at the top of the app page, or Install on the newest STABLE version under Versions.
Tap Install on this device. Scan the QR code with a phone that is signed in to Nomni Store, check the app and version, and tap Approve.
When the download finishes, open the file and tap Update. If Android asks, turn on Install unknown apps for the browser.
Open the POS. On Welcome Back, check APP VERSION at the bottom left, then let it finish syncing before you take orders.
Repeat on every POS device in the venue.
Full steps, including approving from your phone and what to do if the code expires: "Install or update Nomni POS, Nomni KDS or Nomni Kiosk on an Android device with Nomni Store".
What you should see: the first sync after updating can take a little longer than usual, because the POS downloads every product's categories again. This only happens once.
How to leave a category out of a holiday surcharge
Log in to Nomni Console and go to Sales > Surcharge.
Under the General tab, click the pencil icon on your holiday surcharge, or click New Item to create one.
In Exclude Category, pick the categories that shouldn't be surcharged.
Click Save.
On the POS, let it sync, then ring up a test order with one excluded item and one normal item on a day the surcharge applies.
How to take a card payment with Select Card Type
Ring up the order and tap your card payment method.
In the Select Card Type window, tap the customer's card: Visa, MasterCard, American Express, Discover, Diners Club, EFTPOS, Union Pay, JCB or Other Cards.
If your POS shows a surcharge confirmation, check the amount and confirm.
Finish the payment on the terminal as normal.
Australian venues: from 1 October 2026, Nomni POS doesn't add card surcharges for Visa, Mastercard, EFTPOS or All Cards on Australian-dollar accounts. You'll still see Select Card Type, but no surcharge is added for those cards.
Tap Cancel to close the window without taking payment.
Version 2.3.27 (hotfix, 15 October 2026)
Select Card Type only shows when it matters. In 2.3.26 the POS asked for the card type on every card payment. From 2.3.27 it asks only when a card surcharge could apply to the order (card surcharge on, and a surcharge rule that fits this order's amount and source), or when your venue has set the POS to always ask for the card type. Otherwise the payment goes straight to the terminal.
To update, follow "How to update" above. See also "Take a payment on Nomni POS for Android: cash, card, split bills and tips".
If something goes wrong
"Invalid order, unable to start the payment"
This shows if the order changed while the Select Card Type window was open, for example an item was added or the total changed.
Check the order and total are right.
Tap your card payment method again.
Pick the card type.
A holiday surcharge is still added to an excluded category
Check the surcharge has the category under Exclude Category in Nomni Console.
Check the POS shows version 2.3.26.
Close and reopen Nomni POS so it syncs the latest surcharge settings.
If it still happens, email us the order number and the surcharge name.
A multi-day surcharge isn't applying on one of its days
In Nomni Console, open the surcharge and check every day you want is ticked.
Check any start and end dates cover today.
Close and reopen Nomni POS so it syncs.
The wrong card surcharge was added
Check the right card type was picked in Select Card Type.
Check the surcharges set up for each card type.
If you need the payment corrected, email us the order number.
