RFID Scanner to AWS Using Arduino

I have an RFID scanner that uses RS232 to communicate. We need to design a PCB, firmware and an AWS database that have the below functionality.

The user will press a push button that will mean he start the process of scanning different RFID tags, once the push button is clicked, a profile with a unique ID will be created on AWS where the details of every scanned RFID tag will be added to that profile. Details include price and item name. That profile should also contain a field with the total price of all scanned items.

The system will also be interfaced with a simple LCD that shows the total amount of products scanned. The user can remove a product from his stack, that will be done by turning another switch and re-scanning the item that is to be removed.

We will also have an NFC module that will be used for payment at the end. The communicate with AWS will be over WiFi, I am using ES8266-01 for that purpose.

Attached is a diagram that shows how the flow will be.

Deliverables are:

1. PCB layout and schematic.

2. Firmware.

3. AWS database.

Please apply only if you fully understand the project and can do it fast.

Skills: Amazon Web Services, Arduino, Azure, Microcontroller, PCB Layout
