Barcode Scanner and Web Form Interaction

A Python script that scans barcodes using a webcam, interacts with a web form, and optionally saves the scanned data to a CSV file.

Features

• Scans barcodes using a webcam.
• Automatically inputs the barcode data into a web form.
• Optionally saves the scanned barcode data to a CSV file.
• Submits the web form after scanning a barcode.

Requirements

• Python 3.6+
• OpenCV
• pyzbar
• Selenium
• Google Chrome
• ChromeDriver

Installation

1. Clone the repository:

   https://github.com/waldanzubary/scanner-barcode-.git
   

2. Install the required Python packages:

   pip install opencv-python pyzbar selenium

3. Download and install Google Chrome:

   • Google Chrome Download

4. Download ChromeDriver:

   • ChromeDriver Download

   Make sure to download the version of ChromeDriver that matches your installed version of Google Chrome. Add the chromedriver executable to your system's PATH.

Usage

1. Start the local server: Ensure your web application is running locally on http://127.0.0.1:8000.

2. Run the script:

   python scanner.py

   To save scanned barcode data to a CSV file, run the script with the save_to_csv argument set to True:

   python barcode_scanner.py --save_to_csv True

Configuration

• Web Form URL: Modify the URL in the script to match the URL of the web form you want to interact with:

  driver.get("http://127.0.0.1:8000/sales/create")

• Web Form Input Element ID: Ensure the ID of the input element in the web form matches the ID used in the script:

  input_element = driver.find_element(By.ID, "barcode_input")

Troubleshooting

• Webcam not opening: Ensure your webcam is properly connected and not being used by another application.

• ChromeDriver not found: Ensure ChromeDriver is installed and added to your system's PATH.

• Barcode data not being entered into the form: Ensure the URL and input element ID in the script match those of your web form.
