My proof of concept is a solid indication that my project is technically feasible to complete under the time restrictions that I have. The core functionality of scanning RFID chips and uploading to the cloud is working, along with a fully-fledged web app for viewing the results.
The web app is one of the key parts, and it is coming along really well. The design is almost finalized and many of the screens are coming together. The live feed is complete, and it automatically updates whenever a chip is scanned (without refreshing the page). I'm currently working on ways to associate scans with specific events (class meetings) and tracking how many people attend each event. This is where the real value in the product will become apparent.
On the hardware side of things, I have put everything onto a perf board. It now buzzes and flashes an LED when you scan a chip to give you some positive feedback. I'm planning on making the device battery powered. I'm also working on storing the scans in EEPROM memory in the case that the photon is not connected to wifi when scans are recorded. The scans would then be uploaded to the cloud upon reconnection to wifi. I would also like to design an enclosure for the product, but this is on the back burner and we'll see if I have enough time to.
Once I have a working system that I can demonstrate, I would like to show the University in hopes of getting access to the encryption keys for the RFID in MCards. This would allow my system to function with actual MCards instead of generic RFID chips like it's supposed to.
I'm on track to finish my project in time, and I'm looking forward to seeing the finished product!
