In Terminator: The Sarah Connor Chronicles season 1, episode one "Pilot", near the end of the episode John Connor, Sara Connor & Cameron are inside the safety deposit vault of the bank assembling a time machine to go to future, and have the following conversation (as per the Terminator Wiki):
John: So you just have like a account here?
Cameron: Safety deposit box.
Sarah: When did you open that?
Cameron: 1963. (walks by an engraving that says, "THIS STONE WAS SET 1963 THIS DAY MARCH 7")
John: Is that from the future?
Cameron: Can't bring anything through when you come. Not weapons, not clothing. Nothing. You send someone back to build it.
As per Cameron’s last sentence, when any one time travels they cannot bring anything.
But in the last episode of season 2 "Born to Run", Cameron came to Catherine Wiver's building & looked for John Henry. When she found him he asked Cameron
"Will you join us?"
Cameron then took a knife and removed her chip, and gave it to John Henry. So John Henry traveled to the future with Cameron's chip.
So my question is: when time travelling, if they cannot bring anything, how did John Henry take Cameron's chip? Did he use his chip port to take Cameron’s chip to the future?
