SUCCESS TRIAL : READING MAGNETIC STRIPE IN LINUX USING PYTHON

Just do a litle trial,

Trying to read a magnetic stripe card using Chinese MSRE 647 magnetic reader.

This reader is use a usb serial port, so check the usb

$lsusb

returning :
..
Bus 004 Device 005: ID 067b:2303 Prolific Technology, Inc. PL2303 Serial Port

and then look for ttyUSB port used for this device using dmesg command :

...
[111382.037104] pl2303 4-1:1.0: pl2303 converter detected
[111382.049128] usb 4-1: pl2303 converter now attached to ttyUSB0


now lets coding :


#!/usr/bin/env python

import os
import time
import serial

if os.getuid()!=0:
  print "[-] This script requiring root privilege"
  exit(1)

#setup serial connection
ser=serial.Serial(
 port='/dev/ttyUSB0',
 baudrate=9600,
 parity=serial.PARITY_NONE,
 stopbits=serial.STOPBITS_ONE,
 bytesize=serial.EIGHTBITS,
 timeout=0
)

#Check the port
if not ser.isOpen():
 ser.open()

#initialize reader
print "[+] Initiating .."
ser.write("\x1b\x3f\x56")
time.sleep(0.1)

#open connection
print "[+] Open reader connection "
ser.write("\x1b\x31")
time.sleep(0.1)

#read 3 track of card timeout 3 second
print "[+] Swipe card in 3 second"
ser.write("\x1b\x42\x74")
time.sleep(5)
val=""
while ser.inWaiting()>0:
 val += ser.read(1)

#close connection
print "[+] closing connection .."
ser.write("\x1b\x30")
time.sleep(0.1)
# tutup port
ser.close()

# show the card value
print "[+] Card values :\n" + repr(val)

Run the script using root privilege or use sudo,

That for the first step.... next i will try writing to the card or more....
( i think it will be interesting when it connected to arduino ...)
