I used your RFID sample source code on windows(test with python 2.6 & 3.0- same error).
It worked great!, However, there is one error.
Traceback (most recent call last):
File "D:\Python26\Python0\RFID-winsound.py", line 134, in <module>
chr = sys.stdin.read(1)
Can you help please?
I look forward to haring from you soon.
