Python barcode scanner

Price finding runs on Raspberry Pi and works with Chromis POS (open source)

This software can scan barcodes, search through a MySQL database, and display the search results in text format along with product pictures. The project involved the following technologies:

• Image processing: OpenCV-Python, Pillow
• Barcode reader: pyzbar
• Database connector: mysql-connector
• User interface: PySimpleGUI

Setup

1. To install the libraries, run these commands inside your terminal:

pip install PySimpleGUI
pip install opencv-python
pip install pyzbar
pip install mysql-connector
pip install Pillow

2. Install database. I use Chromis POS, or you can edit the SQL query to suit your database.
3. I ran this script on a Raspberry Pi 3 with an LCD monitor and a camera for use in my mini store."
