RFID Reader

Development of a custom RFID Reader script, library and USB Driver for a Debian Server optimized for speed reading.

GitHub repository: https://github.com/RebarDesign/VoltRFID_Linux

Technologies used: Node.js, Express, MySQL, Socket.io, Angular.js, Twitter Bootstrap, C, Linux system calls.

Components

Components:

1. Modified libnfc library allowing concurrent scans from multiple NFC readers. (using fork and Unix pipes).

2. Node.js script on server side handling the readers output and the real-time communication with the back-end server.

3. Node.js back-end server for HTTP requests, database access and events handling (push notification on RFID scan).

4. Front-end written in Angular and Socket.io.

Copy /voltLib files from USB

run as root :

chmod +x installRFID

./installRFID

====

Using an ACR122 device with libnfc and without tag (e.g. to use NFCIP modes or card emulation) needs yet another PCSC-lite tweak: You need to allow usage of CCID Exchange command. To do this, edit libccid_Info.plist configuration file (usually /etc/libccid_Info.plist) and locate "ifdDriverOptions", turn "0x0000" value into 0x0005 to allow CCID exchange and bogus devices (cf previous remark) and restart pcscd daemon.
