Final Year CS Project: Webcam Based Credit Card Reader
There would be several challenges in this project: -
1. Maintaining the security of the credit card information.
2. Making sure that the software works with majority of webcams with various resolutions - VGA to HD
3. Interfacing the webcam with the software and related ecommerce websites.
So, there you go - you have the basic idea and you're free to develop it. If you need more information or want to expand this idea, feel free to ask your questions in this discussion thread 😀
