Which language are you using? Platform?
Try waiting for a while, before reading.

I'm running Slackware 9.1 and tring to listen to the device in a Bash Shell since I don't want to write a program in c to do the job and cause I don't know c

root@jetta:~# tail -f /dev/cua1 > serial.txt

then I scan the card 6 times and then

root@jetta:~# cat serial.txt

And the file is blank

the output I get when I use windows is

000000270F [len=11]
000000270F [len=11]
000000270F [len=11]
