RFID Member Info Portal
Contents
Introduction
The RFID Member Info Portal Project is intended to primarily provide a method for members to use the RFID cards and key fobs to lookup information about their Active Directory Account at Dallas Makerspace, including Voting Rights and Machine Use Rights.
The system will be open source and will use off the shelf components as much as possible.
Requirements
Software
- Reads RFID data from a HID USB 125KHz EM4100 compatible RFID reader
- Software for accessing Active Directory for RFID lookup
- Search Active Directory to ensure RFID matches a current member
- Search Active Directory to list AD Groups
- Logging and data collection
Hardware
- EM4100 compatible 125KHz USB HID RFID reader
- Raspberry Pi 3
- Touchscreen Display
- Network connectivity to the DMS network
- Hardware for powering the device via Power over Ethernet (802.3af)
- Case to protect device from dust and tampering
