I need a small Windows desktop program that helps me confirm packaging quality on the line. The workflow is straightforward: 1. I key-in or paste a number. 2. The app immediately renders that number as a Pharmacode (classic pharmaceutical two-track barcode) on screen. 3. A handheld barcode scanner on COM1 then reads an actual printed Pharmacode. 4. The software compares the scanned value with the one it just generated and shows, right on the main window, whether they match or not. A clear green “OK” or red “Mismatch” banner is enough—no pop-ups or sounds are necessary. I’m flexible on the tech stack; C#, Python with PySerial, or any language that lets you talk to the serial port and draw the barcode cleanly will work. What matters is a reliable executable for Windows, clean code, and a quick, lag-free comparison. Deliverables • Windows installer or portable .exe • Source code with brief read-me on build steps • Simple settings panel (port selection, baud rate) in case the scanner isn’t on COM1 • Clear on-screen visual indicator for match / mismatch If you’ve built serial-port tools or barcode utilities before, this will be a breeze. Let’s get this running smoothly.
