This is a mono-repo that contains hardwire designs, software, and documentation for a complete dual-band RFID access control system. This repo represents the work produced by ECE capstone team 17 during the 2021 - 2022 academic year.
The EPL badge-access system provides a convenient way for EPL managers to ensure that those using equipment in the EPL have been authorized to do so. A small RFID reader is located at each equipmenet station and is programmed to read both PSU-issued student IDs and access cards issued to non-students by the EPL. Depending on the level of strictness required, the RFID reader can either control the power to the equipment via GPIO and relay, or it can simply provide a visual cue to a manager via LEDs on the device.
A central server running on a Raspberry Pi contains an authorization database. The individual RFID readers at each station are wirelessly connected to the server using an 802.11 access point running on the Pi. The authorization server runs a web server which serves an API accessed by the RFID readers.
