Code for listening to a USB RFID reader on the Rascal and then triggering an audio file to play when a card is detected. The code in action:
#!/usr/bin/env python
import sys
import subprocess as subp
sys.stdin = open('/dev/tty0', 'r')
rfid_data = raw_input()
print "Read code from RFID reader: {0}".format(rfid_data)
subp.Popen('aplay --buffer-time=100000 /home/root/calm-16-bit-pcm.wav', shell=True)
