This week, Sophie and I worked on connecting our web application to a commercial RFID reader. We had to deploy our web application through an EC2 instance on AWS in order to get a host URL. In doing so, we were able to successfully send RFID data through a post request to the web application database. The following is a code snippet of our scan.py file, which is responsible for finding the RFID device connected to the RPi and sending the ID and scan time to our URL. 
In the interim demo, we were able to show our web application hosted on AWS and our ability to get scan data from the commercial RFID reader.
I am on schedule for this week. For next week, Sophie and I plan to create an ML model that incorporates live data heavily for demo purposes. We also plan to set up the other RPi in order to get exit times. I want to edit the frontend to be more compatible with mobile devices – it appears a bit different than on the desktop.
