my son came home on leave and tried to get on our wireless but could not and i didn't know the code to unlock it for him... ... ..... but he got on two of my neighbors. . also on the news a while back they were finding small electronic devices hidden on gas pumps that was sending the card info to a parked car not far from pumps. i don't know if it send both the card number and the pin but they had found four of them so far. these were not very big, about 3 inches long and one inch wide and a half inch thick so they were easy to hide robert
