📌 What this application does

My application supports multiple barcode types and displays them directly on your Garmin watch.

The app can generate and display:

1. EAN‑8

2. EAN‑13

3. UPC‑A

4. EAN‑128

5. Code 39

6. Code 93

7. ITF‑14 (always 14 digits, numbers only)

8. Codabar (0–9, A–D, - $ / . + ; must start and end with A–D)

9. Aztec Code

10. Picture mode (upload your own barcode image)

My code generates the barcode and draws it on the screen.

🆕 Advanced barcodes (CIQ2 only)

From version 3.1.0, watches supporting CIQ2 (all models except F3 series, 215×180 and 205×140 formats) can also display:

• QR Code

• PDF417

• DataMatrix

• DotCode

• GS1 DataMatrix

To use these, you must upload an image to my server using this page:

👉 https://riedid74.fr/Barecode/upimage4.html  

Enter the unique identifier shown in the app settings.

📌 Version & Watch Reference

BARECODE Version

Example: V=3.1.0 A=974150

• V = app version

A = internal reference used across all my apps

• I recommend always using the latest version.

Watch Reference

This value appears when the app runs on your watch.

Example: B3291 for a Fenix 6X.

If you install the app with Garmin Express but never launch it on the watch, this field will stay empty.

🔑 License

When the app starts, it checks your license:

• FREE VERSION → no license or invalid license

• PREMIUM VERSION → license is valid

If you enter the license using Garmin Express, it will only update after running the app on the watch.

📧 Save your cards by email

The app can send your cards to your email so you can copy/paste them later.

Make sure you entered a valid email address.

Check your spam folder if needed.

🆘 FIRST: Identify your card type

Install a free barcode scanner on your phone, for example:

Android:

https://play.google.com/store/apps/details?id=com.teacapps.barcodescanner

iPhone:

https://apps.apple.com/us/app/qr-code-barcode-scanner/id1048473097

The scanner will tell you if your card is:

EAN‑8, EAN‑13, UPC‑A, EAN‑128, Code39, ITF‑14, Codabar, etc.

If you still cannot identify it, send me a photo and I will check.

📝 Fill in your cards

Each field corresponds to one barcode type.

Do not mix card types — the app will reset the field.

For each card type:

1️⃣ Enter the labels

Use a semicolon ( ; ) between each label.

Example:

Carrefour;Gym;Library;

2️⃣ Enter the card numbers

Also separated by semicolon.

Example:

12345678;9876543210123;000123456789;

⚠️ You must have the same number of labels and card numbers.

Tips

• If you don’t want to use a card type, enter a single $

• The app supports up to 100 cards

• Free version: full access for 7 days, then only 2 cards remain visible

🖼️ Picture Mode (upload your own barcode)

Some barcodes are too complex or consume too much battery to generate directly.

Picture mode is an alternative.

How to use it:

1. Take a photo of your barcode

2. Crop the image but keep a quiet zone around the code

3. Convert to JPG, black & white, max 100 KB

Upload it using the unique identifier:

4. https://riedid74.fr/Barecode/upimage4.html

5. In the app settings:

   • Picture cards label → enter your label

   • Picture cards name → enter the file name (ex: mycard.jpg;)

Up to 4 picture cards, depending on watch memory.

🧹 Remove picture cache

If your picture displays incorrectly, enable Remove picture cache.

The app will clear cached images, then automatically disable the option.

💾 Backup your cards

Press MENU or Swipe Left inside the app.

Your cards and labels will be emailed to you.

You can also store them manually in a text editor like Notepad++.

⌚ Using the buttons or touchscreen

The app supports both button navigation and touchscreen gestures.
