Set up a barcode scanner and use it to sell

Premium4 min readUpdated October 28, 2026

Check out faster by scanning barcodes with a Bluetooth scanner (Premium feature).

Tunder lets you check out faster by scanning your items' barcodes with a Bluetooth barcode scanner. The Inateck scanner shown on the Hardware page of the website is compatible.

Selling with a barcode scanner is a Premium feature. For now, the camera of your phone or tablet cannot scan barcodes: only a scanner is supported.

Step 1: pair the scanner with your device

The scanner connects directly to your device by Bluetooth, like any Bluetooth accessory. Tunder receives the scanned code as keystrokes, so set the scanner to Bluetooth keyboard mode (see its manual). Once paired, the scanner stays associated with your device: you do not repeat this step every time you use it.

  • On iPhone or iPad

    Pair the scanner from your device's settings.

    • Turn on the scanner and enable its Bluetooth pairing mode.
    • Open the Settings app, tap Bluetooth and make sure Bluetooth is on.
    • In the list of devices, select your scanner.
    • Wait for its status to change to “Connected”.
  • On Android

    Pair the scanner from your device's settings.

    • Turn on the scanner and enable its Bluetooth pairing mode.
    • Open the Settings app, tap Bluetooth (or Connected devices) and make sure Bluetooth is on.
    • Tap “Pair new device”, then select your scanner.
    • Wait for the scanner to appear as connected.

Assign a barcode to an item from the app

For an item to be recognized when scanned, its barcode must be saved in Tunder.

  1. Open the item's form

    Tap the menu icon ☰, then Items, then the item.

  2. Fill in the “Barcode” field

    Type the barcode, or scan it with your scanner to avoid typing errors. Then tap OK at the top right to save the item.

    • A unique code: two items cannot have the same barcode.
    • Premium: without a Premium subscription, the field is greyed out. Tapping it shows you the offer.

Sell with the scanner from the app

Scanning works on the app's sales screen.

  1. Open the sales screen

    Tap the menu icon ☰, then Sell. Stay on this screen: it is the one that receives the scanned code.

  2. Scan an item's barcode

    If the barcode is saved on one of your items, the item is added to the ticket automatically.

    • If the code is saved on no item, nothing happens.
    • With a free account, scanning a recognized code opens the Premium offer instead of adding the item.
  3. Repeat, then check out

    Scan each item, then check out as usual.

Frequently asked questions

Can I scan barcodes with the camera?
No, not for now. Only a Bluetooth barcode scanner is supported.
Is scanning free?
No, selling with a barcode scanner is a Premium feature. Without a Premium subscription, the items' “Barcode” field is greyed out and a scan opens the offer.
I scanned an item but it was not added to the ticket. What should I check?
Check that the scanner is connected by Bluetooth in your device settings, that you are on Tunder's sales screen, that the scanned code is exactly the one on the item's form, and that your Premium subscription is active.
Where do I enter an item's barcode?
In the item's form, “Barcode” field: in the app (☰, Items, the item) or in the back-office (admin.tunder.co: Items, Items tab, the item).
Can I give the same barcode to two items?
No. If the code already exists, Tunder shows “This barcode already exists.” and does not save the item.
How do I find an item from its barcode?
In the back-office (admin.tunder.co): Items, Items tab, type the code in the search box (“Name, category or barcode”).
Do I have to pair the scanner every time I use it?
No. Once paired, the scanner stays associated with your device. It only has to be turned on and within range.
