Branded MMS Coupon Generation with Python and Twilio

The tutorial describes the creation of a digital coupon generation and distribution service using Python, Flask, and Twilio. The application allows users to input their phone number and optional logo image, serial number, and message text to create branded coupons with scannable barcodes. The generated images are then sent via MMS to the user's phone number. The app is deployed on Heroku, where it can be accessed through a web interface. The tutorial provides step-by-step instructions for creating the application, including setting up the Flask app structure, generating coupon images, and sending MMS messages using Twilio.
