Continuity mistake: Just after Joey, Dade, Nikon and Kate finish copying the garbage file onto a disc, Dade reaches inside the booth to grab it. When the camera cuts to the disc, you can see that it is Kate's hand that's grabbing it, not Dade's. You can see a thin black bracelet, long fingernails that are painted white, and a thin silver ring on her thumb.
Visible crew/equipment: When Dade, Phreak, Cereal, and Joey are sitting at Cyberdelia talking at the table, you can see a shadow of the camera on Dade's face.
Plot hole: If Dade is 18, like we find out at the beginning of the movie when his mom says happy birthday, then his probation is over (the judge said "until the time of your 18th birthday") and the terms restricting computer and phone usage no longer apply. The threats by Secret Service about violating his probation are BS since he's not on probation anymore.
Continuity mistake: After Dade and Kate go into the bet, Dade is seen writing notes and passwords on his notebook with a pencil. In the close-up, you can see everything he'd written down is in blue ink.
Answer: Some schools have been known to get students to do some administrative work for them as work experience.
