Inspiration

Access control door scanners

What it does

Scans Mifare Classic NFC cards, sends their ids to watching browsers 👁👄👁

allows exporting as csv

How we built it

using micro python on a raspberry pi pico w, and a mfrc522 nfc reader.

this sends the data (when a new card is detected) to a http server for ingesting.

this sends it to all watching clients

Challenges we ran into

lack of supported libraries

slight mistakes in wiring

websockets autoclosing / timing out

Accomplishments that we're proud of

getting it working

What we learned

fastapi models,

efficient collaborating in a rapidly changing codebase

What's next for RFID-ER

sleep, more features

repos

web (frontend and backend)

micropython picow firmware
