Clint didn't have any on him, not really. He wasn't the sort to wander around with them in his pocket either. Most of the time, when things like this came up, it was a mission and they gave him a memory stick to use. Or a way to transfer the information.
"Hang on," he'd just need to work on that, transfer it to his own personal corner of the SHIELD net and hope that by the time anyone noticed it'd be long since unimportant to discuss. "Okay, you can get it back at that mansion. I can send it to your Stark Pad from there and then you can just say you're appreciating Tony's present."
That was if anyone even bothered to ask. "C'mon, we're better getting the hell outta here now."
