Steps

  3. Create a barcodeOpen Barcode generator, choose a type (Code 128, Code 39, EAN-13, EAN-8, ITF-14) and enter the “Value”. Need many codes: choose “Batch” and load a CSV or Excel file, up to 500 rows.
  4. Scan codesOpen QR / barcode reader, choose an image with a code, paste an image with Ctrl+V, or press “Scan with camera”. Codes are read automatically, no button needed.
  5. Use the resultPress “Copy”, open the link, or “Copy password” for Wi-Fi codes.

Tips

  • A Wi-Fi QR code at the counter: guests scan it to connect, no need to read out the password.
  • Printing small barcodes: print one test label before printing the whole batch.
  • When scanning EAN codes, the tool also checks the last digit to catch misprinted codes.

Good to know

  • EAN and ITF-14 numbers for retail goods must be issued by GS1 Vietnam.
  • Check links carefully before opening them: anyone can print a QR code and stick it over a real one.
  • WPA Wi-Fi passwords need at least 8 characters.
