I think in the best technical way to get through without the agents being able to detect that you have a single satoshi. The most logical would be to memorize the seeds but relying on memory would not leave me 100% at ease. Is there another feasible, safe way?
I'd put on a rubbish USB with a "vault" program & password. Load documents of random stuff maybe resume & whatever else you've got maybe some photos. Straight in a laptop bag in the side pocket with chargers, another small hardive & pen. Could possibly hide the vault on the drive if you wanted to. Put it through as carry on. No one is going to blink an eye. Could also put USB inside a deodorant stick then in your toiletries bag but that's getting extreme.
