My dad can get a laptop with a wireless broadband card from work. he does all the stats for the HS football team, and was wondering if he brought it to the games so he could e-mail the stats if the office would be able to know where the card was used. And that he put it in HIS laptop.

Basically, If my dad gets an internet card from work, will they be able to tell that he used it out of the courtroom (they are meant for the courtroom btw) and in a different computer?
